Booking

one-way vs round-trip flights

One-way versus round-trip flights: flexibility, price, and how to choose.

Quick answer

Choose one-way when your return is uncertain or you want airline freedom — two one-ways buy flexibility. Choose round trip when dates are fixed on one carrier, where it is often simpler and occasionally cheaper. US domestic pricing rarely punishes splitting the trip.

The decision, in one pass

  • Fixed return, one airline preference → round trip
  • Open return, airline choice, or open-jaw routing → two one-ways
  • Price sensitive → compare both totals for your dates

Can I change just one direction of a round trip?

Usually yes — each direction follows change rules separately, but rules vary by fare.

Do one-ways earn the same miles?
