What is a round trip flight and how does it differ from other types of air travel?

A round trip flight is a journey where a passenger flies from one destination to another and then returns to the original starting point. This differs from one-way flights, where the passenger only travels to one destination without returning. Round trip flights are typically booked as a single ticket for both the outbound and return journey, offering convenience and often cost savings compared to booking two separate one-way flights.
