The built in charger slash cup holder on this thing is great. Yeah, it's plastic, no it's not built to be abused but what is these days? It's a really nice feature to have waiting at the gates to change planes or anywhere you have limited access to power. I'm old, fat, and disturbingly clumsy but I had no trouble draggin this thing through ramps, escalators, elevators, moving walkways you name it. Like I said.... Clumsy, so I (repeatedly) bashed the wheels on this thing into walls, smacked the sides into car doors, posts, .......... Other people.... Oops. It took it all like a champ. I'm sure this thing will comply with all the airlines carryon rules.It will expand a bit by use of an expansion zipper so you can over stuff it if need be. If you need an inexpensive carry on that looks great and does the job this is your pick. One last thing. The expanding handle has been mentioned in other reviews as flimsy. Well, it's not made from pillars of steel that's true but I have had no problem with it.Update: July 2024 I read an extensive rather negative review about this piece of luggage and it's really unfortunate. Really my mind gets blown by some of these reviews. One complaint was that the USB charging feature was unreliable. Baloney. What's more likely is your portable battery is unreliable. It's a simple connection ok? Plug the battery in, zip it up in the pocket and then plug your phone , tablet, whatever in the other side. They make a ZILLION of those connectors in thousands of products every day, they rarely fail. Complaint: the color looks faded. What? Look at the picture. That's what you get. I call BS. Complaint: no compartments. Holy crap on a cracker. It's a CARRY ON. carry ons are SMALL. They are supposed to be........First time flyer? Complaint: cheap material and zippers. What are you......a gorilla? Unless you plan on a mid trip temper tantrum where you plan to grab this thing by the compartment divider and throw it at your equally angry spouse, it should last many years. Complaint: the lock was flimsy. WHAT LOCK? I didn't get a lock with mine. I have no idea what the reviewer was expecting from this luggage but it kinda seems like he expected a 300 dollar piece of Samsonite. And.....I gotta tell ya, the reality of that is well......Go ahead and over pay for something else if it makes you feel better.
