A return ticket usually sends you back to the airport where your holiday began. That makes sense for a single-city break, but it can turn a trip across several destinations into an expensive detour. If you arrive in Rome, travel north through Italy and finish in Venice, why spend your final day getting back to Rome just to fly home?
Learning how to book open jaw flights gives you another option: fly into one city and depart from another. The trick is to search for the two flight legs together, then compare the complete journey rather than judging airfare alone.
What an Open-Jaw Flight Actually Looks Like
A typical destination open jaw itinerary might be London to Rome outbound, followed by Venice to London inbound. The journey between Rome and Venice is the open portion of the route. You arrange that ground journey yourself, perhaps by train, while the airfare covers only the flights you selected.
An origin open jaw reverses the idea: you depart from one city and return to another. A double open jaw changes both ends. Airline fare rules distinguish these arrangements, but you do not need to master fare terminology to start searching.
One useful distinction: an open jaw ticket is not necessarily a trip with three or four flights. A conventional open-jaw booking often has two flight journeys, with an unflown gap between destinations. A multi-city search tool can price that arrangement and more complex journeys with additional flights.
How to Book Open Jaw Flights Step by Step
Map the route before opening a flight search
Write down your arrival city, departure city and the places you want to visit between them. Make sure your route moves in a sensible direction. A map may reveal that returning to your starting airport would mean crossing the same region twice.
For example, a ten-day Italy trip could start in Rome, continue by rail to Florence and end in Venice. Search for London–Rome and Venice–London, leaving the Rome-to-Venice portion out of the flight booking. Check realistic rail schedules before committing to dates.
Choose Multi-city instead of Round trip
Open Google Flights or an airline website that supports multi-city bookings. Select Multi-city, enter your first flight from home to the arrival city, and your second flight from the final city back home. Choose dates, passenger numbers and cabin class.
On Google Flights, the multi-city search helps you compare combinations before following a booking option. British Airways also offers a multi-city booking path. Exact controls and participating airlines vary, so check the details displayed at checkout.
Try nearby airports and alternative dates
Flexible flight routes become more practical when you compare nearby airports. Milan, for instance, has multiple airports serving the wider area, but each requires a different journey into the city. A cheaper flight loses its appeal if the airport transfer consumes half a day.
Shift the outbound or inbound date by a day when possible. Compare nonstop options with connecting flights, but pay attention to travel time, not just price. Record airport names carefully; cities with multiple airports can create costly assumptions.
Compare three complete booking strategies
Before buying, price the trip three ways: one multi-city booking containing both flights, two separate one-way tickets, and a traditional round trip from one city. For the round-trip version, add the price and time needed to travel back to that airport.
This is the heart of evaluating multi destination airfare. An open-jaw fare may save money, cost more, or simply make better use of your holiday. There is no universal pricing rule, and fares can change while you search.
Check the booking conditions before paying
Review the operating airlines, baggage allowances, connection times, change fees and refund conditions. Confirm whether the flights will be issued together on one ticket or as separate tickets. A single checkout page does not guarantee the same protection for every connection.
Pay attention to self-transfer itineraries. If you must collect bags, change airports or check in again, allow enough time and understand who is responsible if an earlier flight is late. For further comparisons, see our guide to comparing flight fares.
Measure the Time Saved, Not Just the Fare
Imagine the open-jaw combination costs £60 more than returning from Rome. The round trip appears cheaper. But if traveling from Venice to Rome would require train tickets, a possible hotel night and several hours of travel, the supposedly cheaper airfare might be the more expensive journey overall.
Compare airfare, baggage, ground transport, airport transfers and any extra accommodation. Add a less obvious cost: how much of your limited trip you would spend retracing your steps.
The strongest reason to choose an open jaw itinerary is often efficiency, not a bargain fare. It can turn an awkward circular trip into a smooth journey across a region. For longer holidays, check our tips for planning multi-city trips before deciding where to start and finish.
Common Mistakes That Make Open-Jaw Trips Harder
One mistake is confusing an unflown surface segment with a protected airline connection. If you book Rome on one date and Venice on another, the airline generally does not arrange your travel between those cities. You are responsible for reaching the second departure airport.
Another is scheduling ground travel too tightly. If you plan to reach Venice from Florence on the morning of an international flight, one disrupted train could jeopardize your departure. Spending the preceding night near your departure city is often calmer.
Check entry, transit and visa requirements for every country involved, including overland border crossings. Your passport and itinerary determine what rules apply. Compare fares on a like-for-like basis: the cheapest ticket may exclude the checked bag you need. Our guide to airline baggage rules can help with that final check.
Frequently Asked Questions
Are open-jaw flights cheaper than round-trip flights?
Sometimes, but not consistently. Pricing depends on the route, dates, airline and fare rules. Even when airfare is higher, avoiding a return journey to the first destination may reduce the overall trip cost.
Can I book an open jaw ticket on Google Flights?
Yes. Select Multi-city, enter the outbound flight to your first destination, then enter the return flight from a different destination. Compare results and review the ticketing arrangement before purchasing through the offered booking channel.
Do I need to book the journey between the two cities separately?
Yes, if that segment is not included in your flights. You might travel by train, bus, ferry, car or an additional flight. Plan its timing and cost independently, and leave a buffer before the flight home.
Is an open-jaw booking the same as buying two one-way flights?
Not necessarily. An airline may price two flight journeys together under return or multi-city fare rules, while separate one-way bookings can have different costs and conditions. Compare both options and inspect the issued tickets.
Build the Trip Around Where You Finish
The easiest way to use open-jaw flights is to plan a route that progresses naturally from arrival city to departure city. Search both flights together, compare separate one-ways and a conventional return, then account for transfers between destinations. The best choice fits your actual journey, not simply the fare with the lowest number.
