What is the function of a Jetway or Jetbridge?

The function of a Jetway, or Jetbridge, is to serve as a walkway that connects the gate area of the airport directly to the airplane. This enables passengers to board and deplane the aircraft in a safe and efficient manner. The design of a Jetway allows for a seamless transition between the terminal and the plane, offering protection from external weather conditions and ensuring accessibility for all passengers, including those with reduced mobility.

While the other options describe different aspects of airport operations, they do not accurately capture the specific role of the Jetway. A waiting area for passengers before boarding refers to the space where travelers gather prior to boarding their flight, but this is separate from the connecting function of a Jetway. A designated spot for baggage claim pertains to the area where passengers collect their luggage after a flight, which is unrelated to boarding procedures. Lastly, emergency exits on the plane are crucial for safety but are not associated with the function of a Jetway, which focuses solely on facilitating passenger movement between the terminal and the aircraft.
