Airport procedures involve several steps to ensure a smooth travel experience. First, passengers arrive at the airport and check in for their flight, either at a ticket counter or through a self-service kiosk. After checking in, they must drop off any checked luggage and receive their boarding pass. Next, travelers proceed to the security checkpoint, where they must present their boarding pass and government-issued ID. They will go through a screening process, which includes passing through a metal detector and having their bags scanned. Once cleared, passengers can head to their designated departure gate to wait for boarding.
