A Departure Control System (DCS) automates processing an airlines' airport management operation. This includes managing the information required for airport check-in and printing boarding card, baggage acceptance, boarding, load control and aircraft checks. Additionally and increasingly a DCS for some city-pair sectors may also be connected with immigration control for visa, immigration and passenger no-fly watchlists. Larger international airports will have a range of DCS or a single DCS which each particular airline carrier can integrate with for streamlined operations.
