Booking a one-way ticket
- Some countries require proof of onward travel at check-in or immigration for a one-way arrival — check your destination's entry requirements before you fly.
- Low-cost carriers are typically built around one-way pricing by default; full-service airlines sometimes price one-ways closer to half the return fare rather than a genuine discount.
- Compare the real fares above against a return search for your exact dates — occasionally a return ticket works out cheaper even if you only need one direction.
