Advance Seat Reservation

In the context of aviation, Advance Seat Reservation (ASR) refers to the process by which passengers can select their preferred seats on an aircraft prior to the flight's departure. This service is typically offered by airlines during the booking process, allowing passengers to choose a specific seat based on their personal preferences, such as window or aisle, front or back of the aircraft, or proximity to exits. ASR can be particularly beneficial for passengers traveling in groups who wish to sit together, or for those with specific needs, such as extra legroom or accessibility requirements. Some airlines offer ASR as a complimentary service, while others may charge a fee, particularly for premium seats. The availability of ASR can depend on the specific fare class purchased, the airline's policy, and the aircraft type. It's important to note that even with an advance seat reservation, seats are not guaranteed as airlines may need to change the aircraft type or seating configuration due to operational requirements.
