What does the term "jetway" refer to in an airport setting?

In an airport setting, the term "jetway" refers to a bridge that connects the terminal to the aircraft. This structure, also known as a jet bridge or boarding bridge, allows passengers to safely and comfortably board and disembark from the aircraft without having to walk across the tarmac. The jetway can also be adjusted to accommodate different aircraft sizes and heights, making the boarding process more efficient and secure.

Understanding the function of a jetway is crucial for airport operations and passenger experience, as it facilitates a streamlined process for boarding and deplaning, contributing significantly to overall airport efficiency. Other choices, while related to aviation, do not accurately define what a jetway is, emphasizing the importance of recognizing the unique role that jetways play in airport infrastructure.
