Picture a trip through Italy: you fly into Rome, wander north through Florence and Tuscany by train, and end in Venice. A standard round trip would force you back to Rome just to catch your flight home — a half day and a train fare spent going backward. Open jaw flight tickets exist to solve exactly this, letting you fly into one city and home from another on a single ticket, often for close to the price of an ordinary round trip. Most travelers have never heard the term. Fewer still know that the same booking screen hides several more tricks worth learning.
Quick Answer: What Is an Open Jaw Flight Ticket?
An open jaw flight is a round-trip ticket on which you land in one city and fly home from another — the origin, the destination or both can differ between your outbound and return legs. Instead of doubling back to your arrival city just to catch a plane, you keep moving forward and cover the gap yourself by train, car or a separate flight. Airlines price it as one itinerary rather than two one-way tickets, which is why it frequently costs far less than booking the legs separately and why it lets you see two destinations on a single ticket without paying for an extra flight leg. |
The Three Types of Open Jaw Tickets
The name comes from how the route looks on a map: two flight legs that don't meet, like an open jaw. There are three variations.
A destination open jaw splits the far end of the trip. The classic open jaw flight example: New York → Rome on the way out, Venice → New York on the way home, with Rome to Venice covered on your own. This is the go-to version for travelers touring a region overland.
An origin open jaw splits the home end. You fly New York → Rome, then Rome → Boston — useful when you're relocating, visiting family in another city on the way back, or simply living between two airports.
A double open jaw splits both ends — that's the double open jaw flight meaning in one line. A typical double open jaw example: New York → Rome going out, Venice → Boston coming home. Double open jaw flights are the most flexible construction of the three and the one most likely to need careful price-checking, since more variables are in play.
Open Jaw vs. Round Trip vs. Multi-City Flight Tickets
Travelers often blur these terms, and booking sites don't help, most bury the open jaw option inside the multi-city search form. Technically, an open jaw is one specific shape of a multi-city itinerary. Another way to picture it: an open jaw is a multi-city trip with the middle flight deliberately left out -you travel that segment yourself instead of flying it. The table below separates the three.
Booking type | What it is | When it prices well | Watch out for |
Round trip | Fly out and back between the same two cities | Almost always the baseline; simplest and usually cheapest per mile | Forces backtracking if you're touring a region |
Open jaw | Round trip with one or both ends split between different cities | Regional tours; often prices close to a comparable round trip | The overland gap is yours to cover and protect |
Multi-city | Three or more flight legs strung into one itinerary | Complex trips on one or allied carriers | Can price as separate one-ways if legs don't "construct" together |
The practical takeaway: when you open the multi-city tab, you're not automatically getting magic of multi-city pricing. What you're getting is a form. Whether the fare comes back attractive depends on how the airline's pricing system assembles it-which brings us to the part most guides skip.
Why Open Jaw Flights Are Priced Like Round Trips
Here's the mechanic that makes this whole strategy work. For decades, international fares have commonly been constructed from half round trips: each direction of your journey is priced as half of the applicable round-trip fare for that route, and the halves are added together. Fly into Rome and out of Venice, and you're essentially paying half the New York–Rome round trip plus half the New York–Venice round trip.
Why does that beat booking two one-ways? Because standalone one-way fares, especially on international routes, often carry a premium- airlines price them for business travelers and emergencies, not leisure planning. Two one-way tickets can cost dramatically more than the same legs constructed as a single open jaw itinerary. That's the entire trick: you're accessing round-trip pricing math on a route that isn't literally a round trip.
Two honest caveats, because this doesn't work everywhere. First, the same-region rule of thumb: open jaws tend to price well when both far-end cities sit in the same region. Fly into Rome and out of Tokyo, and the system will usually price it as two expensive one-ways stapled together. Second, the fare-class catch: the very cheapest fare buckets on a route sometimes aren't available for multi-city construction, so the open jaw prices from a higher bucket than the round trip you compared it against. If your multi-city search comes back oddly expensive, this is often why — the mechanics of fare buckets are the same ones we covered in our guide to how airline pricing works.
How to Book Multi-City Flight Tickets (Step by Step)
The order you search matters more than which site you use. Here's the workflow that separates travelers who find the good construction from travelers who assume it doesn't exist.
1. Price the plain round trip first. Search your main city pair as an ordinary return. This number is your baseline — every alternative has to beat it or justify itself.
2. Rebuild the trip in multi-city mode. Switch the booking form to multi-city, enter your open jaw (leg one into your arrival city, leg two home from your departure city) and compare against the baseline. On a well-constructed open jaw, the difference is often modest.
3. Price the same legs as two one-ways. Occasionally — especially on short routes or budget carriers — separate one-way flight tickets genuinely win. You won't know unless you check.
4. Compare totals, not base fares. Add bags, seats and the cost of your overland segment before declaring a winner. A multi city flight ticket that saves $60 in airfare but requires a $90 train isn't a saving.
5. Use area codes to widen the net. Searching city codes that cover every airport in a metro area — NYC for all New York airports, TYO for Tokyo's two — sweeps more combinations in one query than airport-by-airport searching.
Another honest note: complex constructions are where a live agent still out-performs a search box. Multi-city international flight tickets involving mixed carriers, unusual routings or premium cabins are precisely what GDS-trained agents assemble daily. And there's a second reason a call can beat self-serve on these itineraries: consolidator fares. The negotiated wholesale inventory that agencies like Camli hold isn't limited to simple round trips, it can be constructed into open jaw and multi-city itineraries too, sometimes below what the same routing prices are at on public booking sites.
A search box can only show you published fares; an agent can check both. For a simple open jaw, self-serve is fine; a four-leg itinerary across two alliances then a phone call can be the cheapest ten minutes of your trip.
Advanced Booking Hacks That Actually Work
Now the part the title promised. Each of these is legitimate fare construction and each comes with a trade-off worth knowing before you use it.
Let the ground do the flying
The overland gap in an open jaw isn't a compromise; it's often the point. A train from Rome to Venice replaces a flight leg you'd otherwise pay for, turns transit into sightseeing, and eliminates one airport day from your trip. When you plan the jaw around a rail corridor you already wanted to ride, the "gap" costs you nothing you weren't happily spending.
Positioning flights
Sometimes the cheapest multi-city flight tickets don't start from your home airport. If a long-haul fare from a nearby hub is dramatically cheaper, a short, cheap hop to that hub — a positioning flight — can lower the total. The trade-off is serious, though: if you book the positioning flight separately, no airline owes you anything when a delay makes you miss the long-haul. Build in a generous buffer, ideally overnight, or the "saving" can become the most expensive mistake of the trip.
Turn a layover into a stopover
Several international carriers let you extend a connection in their hub city into a stay of a day or more — sometimes at no extra airfare, effectively adding a second destination to one ticket. Programs change, so verify the airline's current stopover policy before you count on it, but when it works, a single multi-city flight ticket quietly becomes a two-city trip.
Mix a budget one-way with an open jaw long-haul
On short intra-regional hops, low-cost carriers sometimes undercut anything a legacy construction can do. Pairing a budget one-way for the gap with an open jaw for the long-haul legs can produce the cheapest total. Keep the two bookings' risks separate in your head: the budget leg has no connection protection to your long-haul, so treat it like a positioning flight and pad the schedule.
When an Open Jaw Is the Wrong Choice
An honest guide says this plainly: sometimes the boring round trip wins. Skip the open jaw when you're visiting one city and coming straight home. Skip it when the overland gap is long, expensive or unreliable — that segment travels at your own risk and cost, with no airline obligation if it goes wrong. Check one-ways first on short domestic routes, where the one-way premium often doesn't exist. And know that changing a multi-leg ticket after you've flown the first segment can be restrictive on many carriers — if your plans are genuinely fluid, a flexible fare matters more than a clever construction.
What Open Jaw Booking Is Not
One distinction matters enough to state directly. Open jaw and multi-city booking are airline-sanctioned fare construction — you fly every segment you bought, exactly as ticketed. That is not the same as hidden-city or throwaway ticketing, where a traveler books segments they intend to skip. Skipping segments violates airline fare rules and can cost you the rest of your itinerary, your miles and, in repeat cases, your standing with the carrier. Everything in this guide works within the rules; that's why it keeps working.
The Bottom Line
Open jaw flight tickets aren't a loophole; they're how international fares have been built for decades, pointed at trips that don't naturally loop back to their starting city. Price the round trip, rebuild it as a jaw, check the one-ways, and judge on the true total airfare, bags and the ground segment together. When the construction gets genuinely complex, let a human with GDS access check it against consolidator inventory as well as published fares — that's exactly the kind of booking Camli's agents handle every day. Where would your first open jaw take you, in one side of a country and out the other?
Frequently Asked Questions
What is an open jaw flight ticket in simple terms?
It's a round trip where the two flight legs don't connect to the same city : you fly into one place and home from another, covering the gap yourself. Airlines price the whole thing as one itinerary, which usually costs far less than buying the legs as separate one-way tickets.
Are open jaw flights more expensive than a round trip?
Often they're surprisingly close, because both are built from the same half-round-trip fare math. An open jaw typically prices well when both cities are in the same region; split the jaw across regions and it can revert to expensive one-way pricing. Always compare it against the plain round trip before booking.
What's the difference between open jaw and multi-city flight tickets?
An open jaw is one specific pattern of a multi-city itinerary: a round trip with one or both ends split between different cities. "Multi-city" is the broader booking form covering any itinerary of two or more legs — including open jaws, triangle routings and longer chains.
How do I find the cheapest multi-city flight tickets?
Price three ways and compare: the plain round trip, the multi-city construction, and the same legs as separate one-ways, then add bags, seats and ground transport to each total. Use metro-area airport codes to widen the search, and for complex international routings, have an agent check the construction before you book.
Do all airlines allow open jaw tickets?
Most full-service international carriers support open jaw construction through their multi-city booking form, though the cheapest fare classes are sometimes excluded from it. Low-cost carriers generally sell point-to-point one-ways instead ; you simply build the same shape from separate tickets and manage the connection risk yourself.
