Open-Jaw Flights Explained
Fly into one city and home from another, then cover the gap yourself. Here is what the ticket actually is, the fare rules that decide whether it prices at all, what one booking protects when a flight is cancelled, and when a different ticket shape does the job better.
What is an open-jaw flight?
An open-jaw ticket is a return ticket where the origin or the destination is not the same in both directions. You fly out to one city, then home from another, while the stretch in between is covered by rail, road, sea or a separate flight rather than by the ticket itself. Because that gap is never flown, reservation systems record it as a surface segment marked ARNK, which stands for arrival unknown.
The important part is what the ticket is, rather than what it looks like on a map. Both flights sit on one booking and the fare is built as a round-trip, so an open-jaw is normally priced below two separate one-way tickets between the same points. That single booking is also what carries the airline's re-routing duty when something goes wrong.
Whether a particular open-jaw prices at all is decided by fare rules rather than by the search engine. The common restriction is that the unflown gap must be shorter than the flown segments, and the cities may have to sit inside the same country or IATA region. When those conditions fail, the fare does not combine and the search quietly falls back to stacking one-ways.
Quick facts: open-jaw tickets
- What it is
- A return ticket whose origin or destination differs between the outbound and the inbound leg.
- Flown segments
- Two, because the middle stretch is covered on the ground rather than in the air.
- How it is priced
- As a round-trip built from two directional fare components, so it usually costs less than two one-ways on the same points.
- The three types
- Destination open-jaw, origin open-jaw and double open-jaw.
- The unflown gap
- Recorded as a surface segment, shown as ARNK in reservation systems.
- Main fare restriction
- The surface segment is commonly required to be shorter than the flown segments, and the points may need to sit inside the same country or IATA region.
- How to search it
- Through the multi-city tab, entering two legs and leaving the middle unflown.
- What one booking protects
- Under EU rules, a cancelled flight gives you a choice of a refund or re-routing, while a missed connection on a single reservation can carry compensation once you arrive more than three hours late.
- What it does not protect
- Anything you booked separately, including the train, bus or ferry that closes the gap.
- Cancelling after booking
- On tickets bought at least seven days before departure to or from the United States, the Department of Transportation requires a 24-hour window to cancel without penalty or to hold the price.
- Last checked
- 20 September 2026, when the airline, government and fare-rule sources named in the source status tables were last read.
Who should read this guide
- Anyone touring a region who does not want to backtrack to the arrival airport
- Travellers weighing one open-jaw ticket against two separate one-ways
- Anyone whose trip ends in a different city from where it started, because of a cruise, a road trip or a rail journey
- Readers who want the fare rules explained rather than a list of tricks
- Anyone who wants to know what the airline owes them when a leg is cancelled
What the ticket actually is
One booking, two flown legs, and a deliberate gap you cross on your own.
The definition in plain terms
A published description of the ticket puts it simply: an open-jaw is a return ticket where the destination or the origin is not the same in both directions. Draw it and the route looks like a jaw that does not close, since the two lines never meet. Everything else about the ticket behaves like an ordinary return.
The surface segment
Reservation systems have to record the unflown stretch somehow, so they insert a surface segment in place of a flight. It appears as ARNK, short for arrival unknown, which tells the system that the passenger reaches the next point without the airline carrying them. That entry is also why the gap is subject to fare rules even though nobody flies it.
Why it stays one ticket
Both flights sit under one booking reference, so the airline treats the journey as a single contract of carriage. When the outbound is cancelled, you are dealing with one carrier about one ticket rather than two sellers pointing at each other. That difference matters more than most fare comparisons, because it decides who pays when the plan breaks.
How it differs from two one-ways
Two one-way tickets can go anywhere, in any combination, on any airlines. An open-jaw cannot, since it has to satisfy the fare rules that let two directional components combine into one return. In exchange you normally get a lower total and a single protected booking, which is the trade at the centre of this whole guide.
The three types of open-jaw
Same idea in three shapes, and the shape decides which fare rules apply.
Destination open-jaw
You leave from and return to the same home city, while the gap sits abroad: into one city, home from another. This is what most travellers mean when they say open-jaw.
Origin open-jaw
The gap sits at your own end instead. You depart from one city at home and come back into a different one, which suits anyone moving base or visiting family on the way.
Double open-jaw
Gaps at both ends, so the outbound and the inbound share neither origin nor destination. Two separate fares sit underneath, though the ticket still travels as one booking.
Reading the shape before you search
Knowing which of the three you need saves time, because the fare rules tighten as the shape gets looser. A destination open-jaw inside one country is the version most likely to price without trouble, while a double open-jaw across two regions is the version most likely to fail and fall back to one-ways.
What stays the same across all three
Each type still flies exactly two segments, still records the gap as a surface segment, and still prices as a return rather than as separate tickets. So the difference between them is where the gap sits, not how the ticket works.
Open-jaw against the other ticket shapes
Six shapes exist, and picking the wrong one is what makes a trip cost more than it should.
The shapes, side by side
| Shape | Route | Flown segments | Typical use |
|---|---|---|---|
| One-way | A to B, with no return booked | One | Open-ended travel, or a move with no return date |
| Round-trip | A to B, then B back to A | Two | A single destination, there and back |
| Open-jaw | A to B, a surface gap, then C back to A | Two, plus an unflown gap | Regional trips where the exit city differs from the arrival city |
| Multi-city | A to B to C to D | Three or more | Several destinations you actually fly between |
| Stopover | A to B, a deliberate pause, then on to C | Two or more, toward one destination | Turning a connection into a short visit |
| Layover | A to C through a short connection | Pass-through only | Changing planes, with no visit intended |
What each one trades off
| Structure | How it prices | Flexibility | Protection if a leg fails |
|---|---|---|---|
| Open-jaw | As one return built from two directional components | Cities flexible, though the dates and the rules are fixed | One contract, so the airline carries the re-routing duty |
| Round-trip | As one return on a single city pair | Simple, until the trip stops being a loop | One contract, as above |
| Two one-ways | Two standalone fares, which may sit on different airlines | Highest, because each leg changes on its own | None across the two tickets, so a missed leg is yours |
| Multi-city | One combined fare across three or more flown legs | Lower, since the legs are locked together | One contract across every leg on the booking |
Where travellers mix them up
A layover is only a connection, so leaving the airport for a night turns it into a stopover instead. A stopover still heads for one final destination, while an open-jaw deliberately skips a segment. Once you would fly three or more segments, the trip has become multi-city rather than open-jaw, and the pricing follows a different path.

Figures this guide does not publish
No fares, no percentage savings and no claim that one airline is cheaper than another. Fares move continuously by route, season and demand, so a number printed here would be wrong within days.
How the fare is built
Nothing about an open-jaw price is invented at the moment you search, so the mechanics are worth knowing.
Two directional components
Airlines file fares for each direction of a city pair, each tied to a fare basis and a booking class. An open-jaw takes one such component for the outbound and another for the inbound, then combines them into a single return. Because the two halves come from different city pairs, the combination is what makes the ticket possible at all.
Inventory decides the price of each half
Each leg is priced from whichever booking class is still open on that flight when you search. As the cheaper classes sell, the system steps that leg up to the next one, so the same open-jaw can look inexpensive one week and steep the next. Nothing here responds to your browsing history, since the movement comes from seats rather than from you.
Combinability is a rule, not a preference
Fare rules state which components may combine, and the search engine simply applies them. When the rules allow it, both legs appear on one ticket at a combined price. When they do not, the engine falls back to stacking one-way fares, which is usually the moment an open-jaw stops looking attractive.
Airlines and alliances
Combination is cleanest where both legs stay inside one airline or one alliance, because those carriers file fares designed to work together. A point-to-point low-cost carrier does the opposite, since it prices every flight on its own and rarely participates in combined fares at all. So the airline mix on your two legs often decides the outcome before the dates do.
What this means at the search stage
Price the trip twice before you commit: once as a single open-jaw, then once as two separate one-ways on whichever carrier is strongest for each leg. Network and alliance routes usually favour the open-jaw, while low-cost routes often favour the pair of one-ways.
The rules that decide whether it prices
When an open-jaw refuses to combine, one of these four conditions is usually the reason.
The gap must be the short side
Published fare-rule descriptions give one restriction more often than any other: the unflown surface segment has to be shorter than the flown segments. A long-haul flight in, then a short hop home from a neighbouring city, satisfies that comfortably. A short flight in, followed by a continent-wide drive, usually does not.
Geography can be fenced
Some fares limit the open-jaw points to the same country, while others allow anywhere inside the same IATA region. Where your two cities straddle that fence, the fare simply will not build, even though the trip makes perfect sense to you. Reading the rule beats guessing, since the boundary is written into the fare rather than into the route.
One airline or one alliance
Two legs on carriers with no commercial relationship have nothing to combine. Where the airlines are partners, or sit inside the same alliance, the filed fares are built to work together and the ticket issues normally.
Award tickets follow their own chart
Where you are paying with miles, the loyalty programme decides whether an open-jaw is permitted and how it is counted, rather than the cash fare rules above. Several programmes allow one open-jaw on a return award, while others do not, so check the programme's own terms before building the itinerary.
When the rules block you
Nothing is lost. Price the same trip as two one-ways, or move one endpoint to a city inside the permitted area, then search again. An open-jaw that will not build is a fare-rule outcome rather than a mistake on your side.
How to book one, step by step
The search is straightforward once you know which tab to use.
- Open the multi-city tab. Although the ticket is a return, it is built as two legs, so the multi-city mode is where you enter it.
- Enter the outbound as leg one. Home to your arrival city, on the date you want to travel.
- Enter the inbound as leg two. Your departure city to home, leaving the middle stretch blank because you are not flying it.
- Check which airlines appear. Where both legs sit inside one airline or alliance, the fare usually combines cleanly.
- Price two one-ways as well. Search each leg on its own, then compare the combined total against the open-jaw fare.
- Price the surface segment. Rail, bus, car hire or a ferry all cost something, so the real comparison includes them.
- Read the fare rules before paying. Baggage, seat selection and change terms decide the true cost as often as the headline fare does.
- Confirm the entry rules for both countries. Two different arrival and departure countries can mean two different requirements.
Where the search often goes wrong
A search that returns nothing usually means the fare rules refused the combination rather than that no flights exist. Try the same shape with one endpoint moved, or split the search into two one-ways to see what the market actually holds.
Booking through an agent
Agents build the same itinerary with a surface segment, so the result is identical to a good online search. What an agent adds is experience of which fares combine, which matters most on complicated double open-jaws.
When it works and when it does not
The shape of your trip answers this faster than any price comparison.
Conditions that favour an open-jaw
- Your arrival and departure cities genuinely differ, so a return would force a backtrack
- Both legs sit inside one airline or one alliance, because that is what lets the fare combine
- The surface segment is shorter than the flights, since that is the usual rule
- Rail, road or sea covers the gap at a sensible cost
- You want both flights on one booking, so that one airline carries the disruption duty
Conditions that favour something else
- The trip visits one city only, because a plain return is simpler and usually cheaper
- Both legs are low-cost carriers that do not file combinable fares
- You would actually fly three or more segments, which makes it a multi-city trip
- The gap is long, expensive or awkward to cross on the ground
- One leg's date may move after booking, so two independent tickets give more room
The honest test
Ask whether you would fly the middle stretch if the ticket included it. When the answer is yes, you need multi-city. When the answer is no, because the train or the drive is part of the trip, the open-jaw is doing exactly the job it exists for.
Itinerary shapes that use it well
Six shapes, described as structures rather than as priced examples.
The rail tour
Fly into the southern end of a country, travel north by train, then fly home from the northern city. Because high-speed rail covers the gap quickly, the surface segment stays short and the fare rules stay satisfied.
The one-way road trip
Land where the drive begins, hire a car, then fly home from where it ends. A one-way rental fee is the cost to weigh, since it often replaces the flight you avoided.
The cruise
Fly to the embarkation port, sail, then fly home from the final port. Cruise itineraries rarely end where they start, so this is the shape they were built for.
The overland leg
Long-haul into one country, overland through a neighbour, then long-haul home from a third city. Check the regional fence in the fare rules first, because this shape crosses it most often.
The two-base work trip
Meetings in one city, then meetings in another, with the transfer by road or rail. One booking keeps the flights protected while the middle stays flexible.
The origin open-jaw
Depart from the city you are leaving behind and return into the one you are moving to. The gap sits at home, so the trip itself stays simple.
What these shapes share
In each case the unflown stretch is something you wanted to travel anyway. That is the test worth applying, since an open-jaw only saves anything when the gap is part of the trip rather than an obstacle inside it.
What one booking protects
This is the part of the open-jaw case that has published rules behind it, rather than a pricing pattern.
Under European rules
European passenger rights guidance states that a cancelled flight leaves the airline owing you a choice: reimbursement of the ticket, re-routing to your final destination at the earliest opportunity, or re-routing later at your convenience. Assistance such as meals and, where the new departure is the next day, accommodation comes on top of that choice.
Why a single reservation matters
The same guidance is explicit that flights booked as part of a single reservation are treated together, so a missed connection that leaves you arriving more than three hours late can carry compensation. An open-jaw is a single reservation by construction, while two separate one-ways are not, which is the clearest difference between the two approaches.
In the United States
The Department of Transportation requires airlines to let you cancel and take a full refund without penalty for 24 hours, or hold the quoted price for 24 hours, where the ticket was bought at least seven days before departure. The same rules entitle passengers to a refund when a flight is cancelled or significantly changed and they choose not to travel, with refunds due within seven business days on card purchases.
Where the protection stops
Nothing on the ticket covers the surface segment, because the airline never agreed to carry you across it. A delayed train or a missed ferry is your own risk, so leave more time in the gap than the timetable suggests and consider cover with our travel insurance calculator.
Rules apply by route, not by preference
European rights attach to flights covered by those rules, while the Department of Transportation rules attach to carriers covered by theirs. Check which set applies to your own itinerary rather than assuming the stronger one does.
Planning the surface segment
The gap is the part of the trip the airline never touches, so it deserves its own plan.
Cost the gap before you compare
A cheaper open-jaw that hands you an expensive rail ticket has not saved anything. Price the train, bus, car hire or ferry first, then add it to the fare before setting the two options side by side. Our trip budget calculator keeps that total honest.
Leave more time than the timetable
Because the surface segment sits outside the ticket, a delay on it can cost you the flight home. Arriving in the departure city the night before is the standard defence, especially when the last flight of the day is the one you hold.
One-way car hire
Dropping a car in a different city usually carries a one-way fee, which varies by company and by distance. Compare that fee against the flight you avoided, since it is the single charge most likely to change the answer. Options are set out in our guide to airport transfers and car rentals.
Borders inside the gap
Crossing a land border between the two flights means meeting that country's entry rules without an airline checking them for you. Confirm what applies with our visa requirements checker before you commit to the shape.
Baggage across the gap
Bags are checked only for the flights on the ticket, so whatever you carry has to travel with you across the surface segment. Rail and coach limits are different from airline limits, which occasionally decides how much luggage the trip can hold.
Common mistakes
Never pricing the alternative
Two one-ways sometimes win, particularly where a low-cost carrier owns one of the legs. Skipping that comparison is the most expensive habit on this page.
Ignoring the gap in the budget
Rail fares, one-way car hire fees and ferry tickets all belong in the total, because the ticket does not include them.
Booking a gap the fare will not allow
Where the surface segment is longer than the flights, the fare often refuses to build, so the search returns nothing useful.
Cutting the gap too fine
A single day between arriving in the departure city and flying home leaves no room when a train is cancelled.
Assuming both countries are the same
Entry rules belong to each country separately, and an open-jaw usually touches at least two of them.
Confusing it with hidden-city ticketing
An open-jaw is a normal, filed fare. Buying a connecting ticket and abandoning the last leg is a different practice that breaks airline conditions.
More traps of this kind are collected in common flight booking mistakes.
Notes by traveller type
The same ticket reads differently depending on how your trip is built.
Independent travellers
Overland between two long-haul legs is where this ticket earns its keep, since the gap is the trip rather than an inconvenience.
Families
One protected booking helps when plans move, though the ground transfer needs planning before the fare is compared.
Business travellers
Two cities, two sets of meetings and no wasted return leg. Flexibility in the fare brand usually matters more than the saving.
Cruise passengers
Embarkation and disembarkation ports rarely match, so the shape fits without any planning effort at all.
Remote workers
Origin and double open-jaws suit anyone whose base changes during the trip, because the gap can sit at either end.
Short-break travellers
A single-city weekend is simpler as a plain return, since there is no backtrack to avoid in the first place.
Documents, money and the ground
Two countries instead of one means two sets of rules, and often two currencies.
Entry rules for each country
Arriving in one country and departing from another puts you under both sets of requirements, so confirm each before you book rather than after. Our visa requirements checker is the quickest way to see what applies.
Onward-ticket requirements
Some countries ask visitors to show they will leave. Immigration New Zealand, for example, tells visa waiver visitors that they need a ticket for travel out of the country and that onward tickets must be paid for before travel. An open-jaw satisfies that kind of requirement neatly, because the departure flight already exists on the booking.
Currency across the gap
A trip that crosses a border on the ground usually crosses a currency too. Track the rate with our currency converter, then read how it feeds into the wider total in how exchange rates affect hotel and flight costs.
Insurance on a two-part trip
Where part of the journey sits outside the ticket, cover for missed connections and cancellations is worth pricing rather than assuming. Compare it with the travel insurance calculator and our travel insurance guide.
Transfers at both ends
Because you land in one city and leave from another, neither airport is the familiar one. Pre-arranged transfers remove the negotiation at the end of a long flight.
Booking checklist
- Arrival and departure cities confirmed as genuinely different, so the ticket has a job to do
- Itinerary built through the multi-city tab as two legs, with the middle left unflown
- Surface segment shorter than the flown legs, because that is the usual fare rule
- Both legs kept inside one airline or alliance wherever possible
- Open-jaw fare priced against two separate one-ways
- Ground transport across the gap priced and, where sensible, booked
- Extra time built in before the return flight, since the gap carries no protection
- Entry and transit rules confirmed for every country the trip touches
- Baggage allowance read for both flights, as well as for the rail or coach leg
- Change and refund terms read before payment, then the 24-hour window noted where it applies
Summary and what to verify
An open-jaw is a return ticket with a deliberate hole in the middle. It exists because travel often runs in one direction, while a plain return assumes you will double back. Since the fare is built as one round-trip from two directional components, it usually undercuts two one-ways on the same points, and it keeps both flights under a single contract.
What the guide cannot tell you is whether your own open-jaw will price. That depends on the fare rules attached to the fares available on your dates, especially the requirement that the surface segment stays shorter than the flights.
The verdict in short
- What the ticket is
- A return whose origin or destination differs by direction, with the unflown stretch recorded as a surface segment.
- What the references support
- Three named types, pricing as a round-trip, and a common rule that the surface segment must be shorter than the flown segments.
- What the regulators publish
- A cancelled flight brings a choice of reimbursement or re-routing under EU rules, while the Department of Transportation requires a 24-hour cancellation window on tickets bought at least seven days ahead.
- Why one booking matters
- Single-reservation itineraries are treated together, so a missed connection that lands you more than three hours late can carry compensation.
- What sits outside the ticket
- The surface segment, along with any train, bus or ferry you booked yourself.
- Figures deliberately omitted
- Fares, percentage savings and any claim that one airline prices open-jaws better than another.
- What to verify before booking
- The fare rules on your own fare, the entry requirements for both countries, the cost of crossing the gap, and the baggage allowance on each leg.
- Last checked

Before you pay
Check the shape: confirm the trip really ends in a different city from where it began.
Compare the alternative: two one-ways sometimes win, so price them properly.
Cost the gap: rail, road or sea belongs in the total, because the ticket excludes it.
Confirm the documents: entry and transit rules come from official sources for each country on the route.
Frequently asked questions
The basics
What is an open-jaw flight in simple terms?
It is a return ticket where you fly into one city and home from another, while you cover the stretch between them yourself by rail, road or sea. Both flights sit on one booking and the fare is built as a round-trip, so the ticket usually costs less than two separate one-ways on the same points.
Why is it called an open jaw?
Because the route drawn on a map looks like a jaw that does not close: two lines that never meet. Reservation systems record the unflown stretch as a surface segment, shown as ARNK, which stands for arrival unknown.
What are the three types of open-jaw?
A destination open-jaw returns to your original city from a different place abroad. An origin open-jaw departs from one home city and returns to another. A double open-jaw has gaps at both ends, so two separate fares sit underneath the one booking.
Is an open-jaw ticket cheaper than a round-trip?
It is priced as a round-trip rather than as two one-ways, so it normally sits close to a standard return on the same route. Whether it beats a plain return depends on your own dates and on which booking classes are open, since a return to a single city is a different product. Price both before deciding.
Booking and fare rules
How do I book an open-jaw flight myself?
Use the multi-city tab on any major search engine. Enter your outbound as the first leg and your return from a different city as the second leg, then leave the middle stretch blank because you are not flying it. The engine prices the two legs as one open-jaw fare when the fare rules allow the combination.
Why will my open-jaw not price?
Usually a fare rule has refused the combination. Published fare-rule descriptions note that the unflown surface segment is commonly required to be shorter than the flown segments, and that the points may have to sit inside the same country or IATA region. Two airlines with no commercial relationship also have nothing to combine.
Can I use two different airlines on an open-jaw?
Only where those airlines file fares that combine, which usually means partners or members of the same alliance. When they do not cooperate, the search falls back to stacking one-way fares, and at that point you are comparing two separate tickets rather than an open-jaw.
Can I book an open-jaw with miles?
Sometimes. Award tickets follow the loyalty programme's own chart and rules rather than the cash fare rules, and programmes differ on whether an open-jaw is permitted on a return award. Check the programme's terms before you build the itinerary.
The gap and the risk
How do I cross the open jaw itself?
By whatever suits the route: train, coach, hire car, ferry or a separately booked flight. None of it sits on the airline ticket, so price it before comparing options and leave more time than the timetable suggests. Where you hire a car in one city and leave it in another, the one-way fee belongs in the comparison.
What happens if my train is late and I miss the flight home?
That risk is yours, because the airline never agreed to carry you across the gap. Arriving in the departure city the night before removes most of the exposure, and insurance that covers missed departures can cover the rest.
Are both flights protected if one is cancelled?
Both flights sit on one reservation, which is what triggers the airline's duty. European passenger rights guidance gives a choice of reimbursement or re-routing when a flight is cancelled, plus assistance, and treats flights booked on a single reservation together. The protection covers the flights on the ticket rather than anything you booked separately.
Can I cancel an open-jaw after booking?
The fare rules on your ticket decide that. On tickets bought at least seven days before departure, the United States Department of Transportation requires covered airlines either to allow cancellation with a full refund for 24 hours or to hold the quoted price for 24 hours, though that rule does not extend to every third-party seller. Outside that window, the fare brand governs.
Comparisons and edge cases
What is the difference between open-jaw and multi-city?
An open-jaw flies two segments with one unflown gap you cross yourself. A multi-city itinerary flies three or more segments between the places you visit. So the test is simple: if you would fly the middle stretch, you need multi-city instead.
Is an open-jaw the same as hidden-city ticketing?
No. An open-jaw is a normal filed fare that airlines sell deliberately. Hidden-city ticketing means buying a connecting fare and abandoning the final segment, which breaks most airlines' conditions of carriage and can cost you the rest of the booking. They are different practices with different consequences.
Does an open-jaw satisfy proof of onward travel?
Usually, because a departure flight already exists on the booking. Immigration New Zealand, for example, tells visa waiver visitors that they need a ticket for travel out of the country and that onward tickets must be paid for before travel. Requirements differ by country, so confirm the rule for your own destination.
Does baggage travel through on an open-jaw?
Bags are checked for the flights on the ticket, so they come off at your arrival city and go back on at the departure city. Whatever you carry travels with you across the gap, which is worth remembering when rail or coach luggage limits differ from airline ones.
Editorial review
- Fact-check methodology
- The definition, the three named types, the ARNK surface segment and the restriction that the unflown segment is commonly shorter than the flown segments are taken from published ticketing references. Passenger rights are quoted from the United States Department of Transportation and from European Union passenger rights guidance, both read on 20 September 2026. The onward-ticket example is quoted from Immigration New Zealand. Booking-window guidance is quoted from Going's 2026 analysis, published 31 July 2026. Fare construction and combinability are described in general terms, because the rules differ by fare.
- Deliberate omissions
- No fares, no percentage savings, no illustrative price tables and no claim that a particular airline prices open-jaws better than another. Prices move continuously, so any figure printed here would mislead.
- Unresolved items
- Whether a specific open-jaw combines is set by the fare rules attached to the fares available on your dates. That cannot be answered generally, so this guide describes the common restrictions rather than predicting an outcome.
- Important limitation
- Fare rules, baggage allowances, loyalty programme terms and entry requirements are set by airlines and governments, and they change. Confirm each one against your own booking and the relevant official source before travelling.
- Corrections and contact
- Spotted something out of date? Tell us through our contact page, then we will check it. How we research and update guides is set out in our editorial policy as well.
This guide is general travel information, rather than advice on your own booking. Your ticket's fare rules and the operating airline's conditions still govern it.
Price it both ways, then book
Build the trip as two legs with the middle left unflown, compare it against two one-ways, then add the cost of crossing the gap before you choose. More guides sit on our blog.
