Cheap One-way Flights

A one-way flight is a ticket that takes you from your starting point to your destination without including a return trip. It’s different from a round-trip ticket, which bundles both your outbound and return flights in one booking. With a one-way ticket, you’re just booking the journey to your destination.

The cost of one-way versus round-trip tickets depends on factors like where you’re flying, which airline you use, and your booking timing. These days, budget airlines and increased competition mean one-way tickets can sometimes be just as affordable, especially for domestic or short-haul flights. That said, for international or long-haul travel, round-trip fares are often the better deal. You can also save by booking two separate one-way tickets on different airlines, a strategy known as a "hacker fare".

Most airlines, including budget carriers that specialize in shorter routes, offer one-way tickets. Popular choices among Cheapflights users include United Airlines and American Airlines, with 21% and 18% of one-way bookings, respectively. However, keep in mind that some destinations with strict visa requirements may require proof of onward travel. While your airline may sell one-way tickets, it’s worth checking if your destination requires additional documentation, particularly for international trips.
