Many travellers, even seasoned ones, fall into the habit of searching for two separate one-way flights.
They think, “Let me check how much it costs to get there,” and only much later do they check and book the return flight.
This browsing pattern makes one-way tickets feel natural, even though it rarely gives the best price, especially on long-haul routes (generally defined as flight time of more than 6 hours for one leg of the journey).
Why people default to one-way tickets
Several familiar habits drive this:
- The belief that one-ways offer more flexibility.
- The assumption that piecing a trip together will uncover cheaper deals.
- Experiences with low-cost carriers, where one-ways are usually proportional.
- Apps and deal alerts that often highlight one-way sales.
However, these assumptions often don’t reflect how long-haul pricing really works.
Choosing a return ticket often delivers far greater savings, and we’ll show you exactly why and how.
Putting it to the test: What we found
To see how big the difference can be, we looked at a sample week in January on several long-haul routes*.
On a Dubai–Los Angeles route, the return ticket came out cheaper by 20% than buying the outbound and inbound legs separately.
On other routes we tested, the price differences between booking two one-way tickets and booking a return can be impressive.
Route | One-way price (total) | Round-trip price | Price difference | Roundtrip is cheaper by (%) |
Riyadh - London Heathrow | $1,075 | $524 | $551 | 51.25% |
Kuwait - Madrid | $1,660 | $748 | $912 | 54.94% |
Dubai - Toronto | $2,101 | $1,336 | $765 | 36.41% |
New Delhi - New York JFK | $2,030 | $1,613 | $417 | 20.54% |
Doha - Manila | $1,230 | $738 | $492 | 40% |
These are just a few examples, but there’s a clear trend here; for long-haul journeys, a return ticket is very often a much better deal.
*For clarity, our comparison only looked at direct flights on the same airlines and close-to-identical schedules. This means the price differences we found are based on the simplest, most like‑for‑like itineraries.
Travellers who are flexible about layovers can save even more, as connecting flights tend to offer lower fares than nonstop options.
What’s behind the price difference?
The main reason comes down to how airlines design their prices.
Return fare pricing logic
A return booking gives the airline a higher level of certainty. When they sell you both legs at once, they can count on filling a seat in each direction, which helps them plan aircraft capacity more efficiently.
That predictability allows them to price return tickets more competitively than single one-way segments.
Because the vast majority of long-haul travellers are taking a round trip rather than relocating one-way, airlines also structure their best fares around these return journeys.
Demand patterns for one-way tickets
One-way tickets, on the other hand, are often used by business travellers or last-minute bookers, so the demand tends to be smaller and more volatile.
Airlines can and do charge more for those single legs to match the demand pattern.
Put simply, a return ticket is sold as a package, and because it guarantees the airline a filled seat in each direction, it usually costs less than paying for each flight separately.
What about short-haul flights?
Short-haul routes can behave a little differently because there is often more competition and more low-cost carriers in the market.
Even so, our sample route between Dubai and Muscat showed you can still save when you book your flight as a return.
It’s one of the more significant price differences we’ve seen in our short-haul test.
Other examples:
Route | One-way price (total) | Round-trip price | Price difference | Roundtrip is cheaper by (%) |
Sharjah - Cairo | $342 | $333 | $9 | 2.06% |
Riyadh - Istanbul | $270 | $259 | $11 | 4.07% |
London Heathrow - Paris | $177 | $158 | $19 | 10.73% |
This suggests that it’s worth checking the return option on shorter routes, even if the gap isn’t always as dramatic as it is on long-haul flights.
How you can use this when you book
The takeaway is, when you plan to fly back to the origin city, purchasing a return ticket instead of two separate one-ways is often the easiest way to save money.
If you know you will be flying out and coming back, start your search with a return ticket for your preferred dates. Then, if you’re curious, compare it with the combined price of two one-way tickets on the same airline and schedule.
In many cases, especially for long-haul journeys, you’ll find that the return ticket wins on price.
On shorter routes, you may at least pay roughly the same while keeping your booking in one simple reservation, or see a small saving. Or, who knows, you may be in for a happy surprise!
