Airports are divided into landside and airside areas.
Airside areas are restricted and accessible only to passengers who have checked in, cleared immigration and security, and hold a valid onward boarding pass. Transit passengers who have cleared transit security may also access airside areas. Checked-in luggage cannot be brought into airside hotels; only cabin luggage is permitted.
Landside areas are accessible to the general public and passengers who have not cleared immigration and passport control.
