A ticket covers travel to a destination without including the return. That ticket is one-way. It suits relocations, open-ended trips, and itineraries that continue to a third place.

One-way fares are sometimes disproportionately expensive compared with round trips on the same route, especially on traditional airlines. Low-cost carriers more often price one-way simply as half of a return logic. Immigration officers may scrutinize one-way international tickets more closely and expect proof of onward travel or sufficient reason for entry.

Travelers using one-way tickets need to plan how they will eventually leave or settle. Flexibility is the main advantage; the lack of a fixed return can also create logistical and administrative complexity. For multi-city routes, combining one-way segments sometimes yields better options than a single round-trip ticket.

A one-way ticket leaves the next decision open.
