A "Departure Airport" is the airport from which a flight takes off. It serves as the starting point for travelers heading to various destinations. Passengers check in, go through security, and board their flights at this location. Departure airports can vary in size, from small regional airports to large international hubs. These airports typically offer various services, including ticketing, baggage handling, and amenities like shops and restaurants. Major departure airports often have multiple terminals to accommodate different airlines and routes. Examples of well-known departure airports include Hartsfield-Jackson Atlanta International Airport and Los Angeles International Airport.
