Outbound passengers arrive at the security check in the public hall and present their passports and flight tickets. As you are no doubt aware, the security check is meticulous for the sake of ensuring the security of all passengers.
After the security check, passengers proceed to the check-in counters of the airline with which they are flying, to check in and obtain a boarding pass.
From there passengers pass through the magnetometer gate to the Departures Hall, where they await the boarding announcement. During this time, passengers can enjoy the duty free shop, other shops and the cafeteria in the hall.
