GREAT super light-weight bag, fits in overhead bin in any way you want to insert it, e.g. wheels out, wheels in, on it's side - it's really easy to make it fit. I can pack a ton of stuff in here, way more than I thought possible given the dimensions. It's holding up very well, I don't think there will be issues with material holding up as some have reported. The only complaint (not worth marking it down in # of stars) is that the roller handle is a single metal bar which makes it a bit of a challenge to keep your briefcase sitting on the bag - my briefcase wants to flip around on the roller handle. If it had a typical wider two bar handle, it would work better - but then it would weigh more and not have the interior room so the trade off is worth it.
