This is an adjustable, universal airline seat belt extender that is 24 inches long. This has been used a handful of times. This will work on Air Canada, American, Alaskan, Delta, JetBlue, United, Virgin and some other international airlines. To the best of my knowledge it will not fit on Southwest airlines. This is much more discrete than having to ask a flight attendant for an extender. This has a few scratches on the buckle as shown in the picture.
