A boarding pass or boarding card is a document provided by an airline during check-in, giving a passenger permission to enter the restricted area of an airport (also known as the airside portion of the 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. A boarding pass may also indicate details of the perks a passenger is entitled to (e.g. lounge access, priority boarding) and is thus presented at the entrance of such facilities to show eligibility.
