What is a boarding pass?

A boarding pass is a document provided by an Airline during check-in, giving a passenger permission to enter the restricted area of an airport and to board the airplane for a particular flight. At a minimum, it identifies the passenger, the flight number, and the date and scheduled time for departure.

Please note that not all airports are equipped for the reading of the  mobile QR code, therefore it is recommended to keep your boarding pass printed and verify Airline rules.
