This service allows you to check in your checked baggage at the airport yourself. The Self-Service Bag Drop is available for flights of chosen airlines. To use this service, passengers need their boarding passes, which can be acquired during on-line check-in or at the Self Check-in kiosk.
The Self-Service Bag Drop machine is situated in the departure hall of Terminal 2. Here the passenger scans the bar code of their boarding ticket, prints the baggage tag and attaches it to their baggage, which then will be sent to the baggage sorting area and loaded onto the aircraft.
