Prompt used

Airline check-in flowchart: the passenger checks in online (48 hours to 1 hour before) or at the airport kiosk/counter, retrieves the booking by PNR, selects a seat (paid or free); international flights require passport and visa details and APIS data sent to the destination. The boarding pass is issued as mobile or print; passengers with checked bags go to bag drop, where bags are weighed (excess fees if over allowance) and tagged, then proceed to security.
