I've flown with this bag about 7 times and have been forced to check it as too large for carry-on 3 times - and these were not tiny regional turbo props, either (most recent plane was an Airbus 330), nor was the bag overstuffed. Disappointing, as I bought it so that I would not have to check it, and I accepted the relatively high price of the bag as what I had to pay to get a quality bag that met my needs. I should have paid a bit more attention to the weasel words "Sized to meet most carry-on requirements" in the text.

Otherwise it is a nice bag, well built and rolls nicely.

Edit to add: this last time, when I got home I emptied it and measured it: in the product description it says "9.5 x 22 x 14 inches" - but I believe those are the inside dimensions of the case, as the exterior, when completely empty and zipped closed, is 10 x 23.5 x 14.25". This may be a game ALL luggage manufacturers play with the airlines, but the airlines are getting increasingly picky, so buyer beware.
