I am flying to PR for a cruise. I am concerned because I wanted to use my 21" suitcase as a carry-on. However, while flying to Hungary, I used a 21" which expanded and they made me check it. I guess it became too wide once it was expanded. Has anyone experienced being asked to check a 21" or 22" piece of luggage on an airline?
As the previous poster mentioned, it often depends on the flight and the airline. I had a 22" that I fit into their tester and it just fit, then I saw a young girl with a bag that had to be several inches too large. I asked her how she could use it as a carry-on and not get questioned; she said she never had a problem.
Of course, I'm a 58 yr old beer-bellied guy; she was an attractive young woman. I suppose that might have something to do with it!
Golden, the maximum size for a carryon bag is 22 L x 14 W x 9 D. Carryon bags come shallow enough, so when they are expanded, they must be checked. The length of that bag is irrelevant because you said it is only 21 inches long.
I don't care how small a bag is; I am going to check it every time. Years ago I flagged a TSA agent by not putting my suitcase on the x-ray belt. Ever since, my family has only carried on luggage that way when we flew to Gainesville's regional airport, which has no Southwest gates, and back home from there.
