What is a jetbridge used for?

A jetbridge, commonly found at airports, serves a crucial function by providing protected access between the terminal gate and the aircraft. This structure allows passengers to board and disembark from the plane in a safe and sheltered environment, shielding them from weather conditions such as rain, snow, or extreme temperatures. It ensures a smoother transition from the terminal to the aircraft, enhancing the travel experience by minimizing exposure to the elements and improving overall safety.

While other options mention aspects related to airport operations, they do not embody the primary purpose of the jetbridge. Connecting an aircraft to ground services focuses more on servicing aircraft rather than passenger access, therefore it does not accurately define the jetbridge's function. Serving as a boarding area for non-rev passengers is not the primary role of a jetbridge, as the structure is for all passengers regardless of their ticket status. Lastly, facilitating luggage storage pertains to the ground operations of an airline, which is unrelated to the direct purpose of the jetbridge.
