At the airport, a gate, also known as a boarding gate, is the specific area in an airport where passengers wait and board a plane for a flight. Gates are located in concourses, which are found in terminals of the airport; each flight will have a different boarding gate number, though a gate can be used again after a flight departs.
Passengers will typically wait at the gate until the plane is ready to be boarded; the gate is located in the airport area past security. The connecting path that allows passengers to board the aircraft from the gate is usually the jet bridge.
