A round-trip flight is a type of airline ticket that allows a passenger to travel to a destination and then return to the original departure point. This ticket typically includes two segments: the outbound flight to the destination and the return flight back home. Round-trip flights are often more economical than purchasing two one-way tickets. Travelers can book round-trip flights through various airlines and travel agencies. These flights usually have specific dates for departure and return, and passengers must adhere to these schedules. Changes to the itinerary may incur additional fees, depending on the airline's policies.
