RT means “Round Trip.” It refers to a type of travel itinerary where a passenger travels from one destination to another and then returns to the original departure point. In a round trip, unlike an open-jaw ticket, the traveler completes a full loop, departing from and eventually returning to the same location. Round trips are commonly used for vacations, business trips, and other types of travel where the traveler’s journey involves visiting a destination and then returning home.
