A boarding pass is a document provided by an airline during check-in giving a passenger permission 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. Boarding passes are always required to board a flight. Often, airlines accept either paper or electronic boarding passes (on phone or tablet).
