domestic services introduced a self-check-in process allowing passengers with bags to arrive and check-in at the self-service kiosks up to 10 min prior to departure time. Passengers then attach the baggage tag and drop the bag themselves at the baggage drop belt. However, passengers without checked luggage can go straight to the lounge (if entitled to lounge access) and check in at the kiosk there using their ePass (a small RFID device only for its premium customers) or proceed straight to the departure gate when boarding using either their ePass or mPass (an application which can be downloaded or installed onto mobile phones to work as an electronic boarding pass).
