Airline Reservation System ER Diagram

An Airline Reservation System ER diagram typically includes key entities such as Flights, Passengers, Reservations, and Aircraft. Flights are connected to specific Routes, which store information like origin and destination airports. Passengers are associated with Reservations, indicating which seats they occupy on particular flights. Each Reservation maintains details such as booking date, payment information, and assigned seat. Aircraft entities may link to additional data like plane model, capacity, and maintenance schedules, ensuring safe and organized operations.
