How Long Are the Seat Belts on My Airplane?

The answer to this question varies by airline and by type of aircraft.

Most airlines do not provide information about seat belt lengths on their websites. You can get current seat belt information by contacting your airline, and it's always a good idea to do this whenever you have any questions or concerns about your tickets, itinerary or flight. This process may take some time, particularly if you contact your airline by email or happen to reach a customer service agent by telephone who does not know the answer to your question.

To help you find up-to-date seat belt information, we contacted several North American airlines to find out how long their seat belts are, on average, and whether they provide seat belt extenders.

Several airlines mentioned special policies that apply to the use of seat belt extenders. For example, Delta Air Lines does not permit passengers to use their own personal extenders, citing "FAA regulations" as the reason for this ban. Alaska Airlines does not allow passengers to use seat belt extenders if they are sitting in an exit row.

While this information is current as of this writing, please bear in mind that airlines purchase new aircraft and upgrade their existing equipment on a regular basis, so your experience may differ from the data presented here.
