Qatar Aviation Services at Doha’s International airport provides all services from Passenger Services to Cargo Handling, IATA-Ticketing to Executive Handling, for all scheduled and ad hoc flights into Qatar. Employing more than 1,700 people in an operation that runs 24 hours a day, 365 days a year, Qatar Aviation Services (QAS) looks after every passenger, bag and piece of cargo that passes through Doha International Airport. Formed in 2000 and employing 1,300 staff, QAS is a wholly owned subsidiary of Qatar Airways that provides services to every airline operating through Doha International Airport. As the sole ground handling agent, it is therefore responsible for all passenger, aircraft, and cargo handling. QAS is made up of four units:Ground Services, which manages general operations on the airside.Customer Services, which handles passengers.Cargo Services, which handles cargo throughput.Engineering, which supplies, operates and maintains all vehicles and equipment operating around the airside area.QAS’ Operation Control Center and computerized gate operating systems at DIA. The center allows QAS to monitor and direct aircraft around the airport as effectively as possible. This will become increasingly important in the coming years given the rapid increase in traffic that is forecast to pass through the airport. The Operation Control Center also houses the new Gate Operating System that manages the parking of aircraft in all 19 bays of airport. It uses a computer-controlled screen that interacts with the pilot, thus eliminating the need for human assistance to guide the pilot to the bay.
