This is the exact bag that I needed for travel. I hate checking bags when I fly so this was a good investment ($47 is what I paid for the black version). The bag wheels roll smoothly, the handle is big enough and long enough to hold/roll comfortably (I'm 6'3"). On the lid there are two compartments on the outside and one big mesh one on the inside. There are two elastic straps on the inside of the main compartment for holding your stuff tightly. The retractable handle has a zipper cover as well. I have been handling it and the construction feels sturdy and the zippers gave me no problems (although they feel a little stiff around corners).

The reason I gave it 4 stars is that I have one concern about the dimensions of this bag. From front to back it's just under 9 inches (that's good, it has a little room for fill). From side to side it's 13.5 inches (not 14) from my measure -- again, that's fine, leaves a little room for bloat. From top to bottom when standing the bag is closer to 25 inches, not 22! This takes into consideration the standing height (including on it's wheels). Is there a chance it might not be accepted as a carry-on? Possibly, but doubt it.

Overall, I would recommend this bag. I'll update with a comment if I have any problems flying later!
