How to Book One-Way Flights Without Overpaying
One-way pricing works differently across airlines — some price it transparently, while on others a genuine one-way costs nearly as much as a full return, making the return fare the better deal even if you only need one direction.
1. Compare the one-way price against half a return fare
On some full-service airlines, a round-trip divided in half is cheaper than a genuine one-way — check both before booking.
2. Check low-cost carriers separately
Budget airlines typically price one-ways transparently as half (or close to half) of a return, unlike some full-service carriers.
3. Consider two separate one-ways with different airlines
If neither airline's own round-trip works for your dates, booking two one-way tickets on different carriers can sometimes beat a single round-trip fare.
4. Check entry requirements for one-way international travel
Some countries require proof of onward or return travel at immigration — check this before booking a genuine one-way internationally.
5. Confirm baggage rules apply the same to one-way fares
Some promotional baggage allowances are tied to round-trip bookings only — check this specifically for a one-way ticket.
Quick tips
- Never assume a one-way is automatically half the round-trip price — check both explicitly, especially on full-service airlines.
- Booking two one-ways with different airlines can also give you more flexibility if your return date isn't fixed yet.
- Some countries' immigration checks require proof of onward travel — a genuine one-way ticket can cause a problem at check-in if you can't show this.
- Compare the total cost of two one-ways including separate booking fees, not just the base fares.
- Low-cost carriers are usually the most straightforward for one-way pricing, since they don't rely on round-trip discounting the way some full-service airlines do.
