I wish the airlines would enforce their own carry-on policies. It is irritating to stand waiting in an aisle while someone tries to wrestle a bag the size of a foot locker into an overhead bin. I bought this because the dimensions fit the published regulations. It fits easily into a bin or under a seat, even fully loaded.
