One-way or round trip? What’s the difference?
A one-way flight ticket is a ticket that will take you from your departure airport to your destination but it does not include a return flight. A round trip is a journey to a destination and back again, most often between the same two cities.
If you are flying from New York to Los Angeles you can buy a one way ticket if you are going to stay there for good or plan the return separately. If you are going on a week long vacation a round trip ticket may be more convenient.
When comparing one way vs round trip flights, be aware that one is not always cheaper. The price that you pay depends on the airline, the route, the dates of your trip, the demand and the conditions of the ticket.
One Way or Round Trip Airfare: Which Costs Less?
Round trip airfare price difference depends on itinerary. One way vs Some airlines will have competitive one-way prices. Some will price a round trip attractively. The only way to know for sure is to compare total prices for your specific dates.
Before you book, a few things to consider:
- Travel Dates: Flying on different days can be a huge difference in price.
- Airline & Route: Sometimes the same flight will have different prices on different airlines.
- Baggage and extras: When comparing tickets, add in checked bags, seat selection and other fees.
- Flexibility: See the rules for changing or canceling your booking.
- Return plans: If you don’t know when you will return, a one-way ticket may be more flexible, but fares may be higher in the future.
