What appears on the boarding pass?

The boarding pass is a crucial document that serves multiple functions for both passengers and airline staff. It typically contains essential information necessary for boarding the aircraft. The passenger name is included to identify who is authorized to board that specific flight. The flight number provides a unique identifier for the flight itself, making it easy to track and reference. Additionally, gate information is vital as it directs passengers to the correct boarding location at the airport.

In contrast, while other options might seem relevant to the overall travel experience, they do not appear on the boarding pass. For instance, flight duration and altitude are not included on the boarding pass, as those details are more relevant to in-flight announcements or the airline's informational displays. Passenger food preferences and in-flight entertainment options are also not listed on the boarding pass; these cater to the experience during the flight rather than the boarding process itself. Thus, the correct choice highlights the most pertinent information that passengers need to board their flight properly.
