What Does “Open Jaw” Mean in Flight Booking?

An open-jaw flight is a ticket where you fly into one city and fly home from a different city, with the gap between the two filled by your own travel — by train, car, bus, or boat — rather than by another flight.

If you’ve come across the term while searching for flights and weren’t sure what it meant, this is the simple version. The rest of this guide explains where the name comes from, how it actually works, and how it’s different from the other flight types you’ll come across when booking.

Where Does the Name Come From?

The term comes from how the route looks when drawn on a map. A standard round trip forms a straight line out and back, or a closed loop if you draw it as two separate outbound and return paths overlapping. An open-jaw route instead looks like an open mouth or a pair of jaws — two lines that spread apart rather than meeting, representing the gap between where you land and where you eventually depart from.

A simple example:

• Round trip: London → Rome → London (same city both ways)
• Open-jaw: London → Rome … (you travel overland) … Florence → London (different cities)

You fly into Rome, make your own way to Florence however you like, and fly home from Florence instead of flying back to Rome first.

How Is This Different From a Normal Flight?

A round trip takes you from your home city to one destination and back to that same home city. This is the most common and familiar type of ticket.

A one-way flight takes you from one city to another, with no return included at all.

An open-jaw sits between these two ideas — it’s genuinely two flights (an outbound and a return), like a round trip, but the two flights don’t connect to the same city on the destination end. You choose to fly into one place and out of a different one.

A multi-city flight is a related but broader concept — it involves flying between several destinations as part of the same itinerary, with actual flights connecting each city. Open-jaw is really the simplest version of this idea, involving just one “gap” filled by your own ground travel rather than another flight.

A Few More Examples

European city-hopping: Fly into Barcelona, travel by train through Valencia and Granada, fly home from Madrid.

US road trip: Fly into Seattle, drive down the Pacific Coast Highway, fly home from Los Angeles.

Island-to-mainland travel: Fly into Bali, take ferries and trains through Indonesia, fly home from Jakarta.

In each case, there’s no flight directly connecting the two cities in the middle of the trip — that part is entirely up to you to plan and travel independently.

Why Would Someone Book a Flight Like This?

To avoid backtracking. If your trip naturally moves from one city to another, flying back to your starting point just to catch your return flight wastes time and often money.

Because it’s often priced similarly to a standard round trip. This is the detail that surprises a lot of people — flying into one city and out of another usually isn’t dramatically more expensive than a normal round trip on the same airline, even though it might sound like it should be.

It suits any trip that naturally moves in one direction — road trips, rail journeys through multiple countries, or any itinerary where you’re not planning to return to your first destination before heading home.

Is It the Same as a “Multi-City” Search?

They’re closely related, and in most flight search tools, you’ll use the same “multi-city” search mode to book an open-jaw ticket — you’re just adding one extra city rather than several. The difference is really about the itinerary itself: a true multi-city trip involves flying between multiple destinations, while an open-jaw trip involves just the one gap, filled by your own travel rather than a flight.

Frequently Asked Questions

Q: Is “open-jaw” an official airline term, or just travel slang? It’s a genuine, widely used industry term, not just informal slang — you’ll see it used by airlines, travel agents, and booking platforms, though it’s not always the label shown directly in a search interface (which more often just says “multi-city”).

Q: Do I book an open-jaw flight differently from a normal flight? You typically use the “multi-city” search option on most booking sites, setting your outbound destination and your return departure city as two different airports, rather than the standard “round trip” search.

Q: Can the two cities be in different countries? Yes, absolutely — in fact, this is one of the most common uses of an open-jaw ticket, particularly for trips spanning multiple countries connected by train or road travel.

Q: Is there a limit to how far apart the two cities can be? No formal limit, though it’s worth thinking practically about how you’ll actually travel between them — an open-jaw only makes sense if the gap between your two cities is realistically coverable by your own transport.

Final Thoughts

“Open-jaw” is simply the name for a flight into one city and home from another, named for the shape it makes on a map. It’s one of the simplest and most useful tools in flight planning once you know it exists — particularly for any trip that naturally moves in one direction rather than looping back to where it started.
