What Is Jet Bridge? Definition & Meaning in Aviation
A jet bridge (or boarding bridge) is a covered walkway that connects an aircraft door directly to the terminal.
In plain language
It lets passengers board without going outside. Airports have a limited number of jet bridges, so some flights use remote stands and buses.
Example
A flight assigned to a gate with a jet bridge usually boards faster than one parked on the apron.
Why it matters
Whether your flight uses a jet bridge affects boarding speed and how easy it is for passengers who need assistance. It is also why gate availability can delay an arrival.
