The system works entirely by touchscreen operation. You can select your destination from the options on the screen, quickly complete the check-in procedure, take your boarding card and go straight to the boarding gate. Passengers with luggage to check can get their boarding card and then drop off their bags at the Online Check-in counters, without waiting in a queue, before continuing on to security control. The counters in block C at Sabiha Gökçen Airport are reserves for passengers who have checked in online.
