I just bought 2 yesterday taking the salesperson's advice. But when I brought it home and compared it with my current 22", it did look a lot bigger. So we took it to the airport and put it to the test. The height and depth part is fine. Just the width is about a couple inches too thick.

I think you can get it past check-in, but I don't think it'll pass with the TSA. Gonna return it today and get the carry on approved one instead.
