Open-Jaw Flights: The Trick That Saves Money and Adds Destinations

May 21, 2026

Most people book flights as straightforward return trips: outbound from city A to city B, inbound from city B back to A. An open-jaw ticket breaks that symmetry in a deliberate, money-saving way. The concept is simple once you understand it, and the savings can be substantial.

What Is an Open-Jaw Flight?

An open-jaw ticket is a return fare where the departure or arrival point differs on one leg. There are two common variations. A surface open jaw has you flying out from one city and returning from a different city—for example, flying from London Heathrow (LHR) to Rome Fiumicino (FCO), travelling overland through Italy, and flying home from Naples (NAP). A double open jaw has you departing from one city in your home country, arriving at one destination, then departing from a different destination and returning to a different city at home.

Airlines typically price open-jaw fares by combining half of each applicable return fare. Because the "unused" surface segment—the overland stretch you fill yourself by train, bus, or cheap domestic flight—costs the airline nothing, you pay for air miles actually flown. This pricing logic is what creates the savings.

A Concrete Example With Real Numbers

Consider a traveller based in Manchester (MAN) wanting to explore Spain. A return from MAN to Madrid (MAD) on Iberia (IB) might price at £210. A return from MAN to Barcelona (BCN) on Vueling (VY) might price at £185. However, an open-jaw from MAN to MAD, returning from BCN to MAN, could price at £195—less than either return individually in some seasons. The traveller gets to explore the stretch from Madrid to Barcelona by AVE high-speed rail (a scenic four-hour journey costing €35–€50) and avoids doubling back to their starting point.

The math works because airlines often price the "half return" (one direction of a return fare) at 55–60% of the full return, meaning two half-returns can come in below the sum of the two separate one-way vs return flights fares.

When Open-Jaw Tickets Deliver the Most Value

Open-jaw pricing is especially powerful on long-haul routes. A traveller flying from New York (JFK) to Tokyo Narita (NRT), then exiting from Osaka (KIX) back to JFK, may find the open-jaw fare is within $50 of a standard return—despite adding an entirely new city and eliminating a backtrack by shinkansen. The overland journey from Tokyo to Osaka takes 2 hours 15 minutes by Nozomi bullet train and costs around ¥14,000 (approximately $95). Compare that to the cost and time of flying back to Tokyo simply to catch your original return flight.

In Southeast Asia the economics are even better. Fly into Bangkok (BKK), travel overland through Chiang Mai, Luang Prabang, and Hanoi, then exit from Ho Chi Minh City (SGN) back to your home country. Done as separate one-ways this itinerary is expensive; structured as an open jaw with a regional carrier like Thai Airways (TG) or Vietnam Airlines (VN), the fare can be remarkably competitive.

How to Search for Open-Jaw Fares

The frustrating reality is that most flight search engines either hide open-jaw options or require you to know to look for them. Google Flights' multi-city flights tool supports open-jaw searches but does not always find the combined fare pricing—it often quotes two separate one-ways instead. Skyscanner's multi-city mode is similar: useful, but it quotes independent segments.

The cleanest approach is to search individual airline booking systems directly for multi-city or open-jaw fare types, particularly for long-haul routes. Airlines like Lufthansa (LH), British Airways (BA), and Cathay Pacific (CX) have specific open-jaw fare rules built into their fare basis codes, and their own booking engines surface these correctly.

For cross-market fare comparison on the individual legs, RegionFare helps identify whether booking the LHR–NRT half of your open jaw through the Japanese yen storefront saves money compared to the sterling storefront—differences of 8–15% are common on long-haul fares when compared across markets.

Common Pitfalls

The surface segment must be realistic. If you book an open jaw that requires travelling from Naples to Rome overnight to catch a 6am departure, you have created a stressful situation for a small saving. Build in a night's accommodation buffer on both ends of the surface segment.

Baggage rules apply to the whole ticket. Check-in baggage is almost always included end-to-end; you will not need to recheck at the surface segment city. However, if you add a separate cheap domestic flight within the surface gap, that is on a separate booking and carries its own baggage rules.

Open-jaw fares are usually non-refundable or carry high change fees. The saving comes with reduced flexibility, so only book once your itinerary is firm.

The Takeaway

Open-jaw tickets are one of the most underused tools in a traveller's arsenal. They reward people who want to see more places rather than retrace their steps, and they often cost the same as or less than a simple return. The key is knowing to search for them explicitly and understanding how airline pricing combines the two half-legs. Once you book your first open jaw, you will find it difficult to go back to the standard out-and-back.
