A round-trip flight is a type of airline ticket that allows a passenger to travel to a destination and then return to their 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 for various reasons, such as vacations, business trips, or visiting family. Airlines usually offer different classes of service, such as economy, business, and first class, allowing passengers to choose based on their budget and comfort preferences.
