This bag fits wheels-first in the overhead compartment of 737 aircraft.  It's deep enough and wide enough to fit plenty of clothing.  It does lack a good interior zipped, mesh storage area for shorts, however.  It does have  separate zipped wet area and two smaller mesh zippered areaa.  The handle feels a little flimsy (Samsonite has tried to keep the bags weight to a minimum), but it has worked fine so far.  The biggest issue is that when you put a laptop in the front exterior pocket, this bag easily tips forward.  Would be better if it had just a little lean toward the back.  But still, I really like this bag.  It glides easily, can roll sideways through airplane aisles, has a very light empty weight, and fits easily into overhead compartments.
