Round trip

A round trip is an itinerary in which a passenger travels to a destination and then returns to the original starting point. 

The dates and destinations of both the outbound and return flights are typically determined in advance when booking the trip, although some flexibility may be allowed depending on the airline or travel service.

Airlines, train companies, and other transportation providers offer round-trip tickets, which often cost less than two separate one-way tickets.

Passengers usually use the same carrier during the journey, but other carriers may offer open-jaw round trips, where the departure and return cities differ (flying into one city and out of another).

Round-trip tickets help airlines fill seats for both the outbound and return legs of the journey, ensuring better load factors and more predictable bookings. Passengers also benefit from round trips as they can plan both parts of their journey at once, saving time and hassle.
