I bought this for a 10-day trip to the Caribbean, and it fit *exactly* perfectly in the overhead bins on all four of my flights. An inch more & it would have been too big! So, for people wanting to maximize overhead bin space, this is it. Does the trick. I flew JetBlue and United, and was in planes that have only one aisle, with three seats on either side. So, not huge planes but not puddle-jumpers either. To note: I'm sure this bag would be much too big for carrying onto a tiny regional plane.

When ordering this bag, I accidentally bought the Maxlite 4 International suitcase at first, so I got a chance to compare their sizes. This bag is about 1.5 - 2" taller, but otherwise exactly the same width & depth-wise. Each bag is 13" wide, about 8-9" deep, and the the International bag is 20.25" tall, whereas this one is 22.25" tall (not including the fabric top handle, but including wheels). Photos attached.

The little semi-hidden compartment on the front to put your passport or boarding ticket(s) is pretty awesome. I didn't end up using it because I don't want to be separated from my passport, and I used mobile tickets, but still a cool feature. I put cough drops and some travel tissues in it instead.

I was able to fit a crap ton of stuff into this bag, which was great because the weather ranged from hot & sunny, to windy & rainy during my trip -- and I had a friend's wedding to go to, so I needed nice clothing in addition to my beach gear. I fit 6 dresses, 1 pair of shorts, 3 shirts, 2 cardigans, 1 shawl, 1 bulky woven cover-up, 3 swim suits, 4 pairs of socks, sandals, an umbrella, a solar charger, 2 books, 2 notebooks, 2 bottles of sunscreen, basic toiletries, and several bottles of cold & allergy meds into this bag. (I definitely didn't need all of that stuff in retrospect, but the point is: it all fit). I used a set of Shacke Pak packing cubes to fit & organize all of that, and it worked like a dream.

But -- a note about packing cubes & this carry-on bag! Don't get a set that includes Large or XL cubes. They won't fit! I was able to fit three Medium cubes and 1 Small cube, and even that was pushing it. You definitely cannot fit more than that in here. If you tried to use a Large cube, that would just basically be your whole suitcase. So, just to warn you :)

The (few) cons:

Size - almost too big.
What I didn't like is that my bag seemed to be the biggest, or among the biggest, out of all of the other passengers' carry-on bags on each of my four flights. Made me a little nervous that this is going to be "too big" soon for many airlines as they keep squeezing sizes & our wallets. Part of me wishes I would have gotten the international one instead, just to be safe. That's not Travelpro's fault, but it is something I'm anxious about when I think about this bag.

Loose threads
Another small aside is that, when the bag arrived, it had 10-15 different loose threads all over it. They weren't defects or damaged parts, just the ends/beginnings of different seams that hadn't been properly trimmed. The threads did look as though it was falling apart a bit, and if you don't know how to differentiate seams from fabric, I could see how someone might be worried that they received a defective product. Luckily, I just took out my sewing scissors and trimmed the ends, and now it's better than new.

Don't compress the straps too much!
I used Shacke Pak packing cubes with this bag, and then used the built-in compression straps as well. Mistake! You don't need to use both. And in my case, I almost damaged my bag by doing that. I pulled the compression straps really tight to flatten the packing cubes down and then when I looked behind my bag after I got off my first flight, it was warping inwards! The entire back panel of the bag was pulling in around the middle, causing a sloping effect if you look from the side. So I quickly unclasped those straps and that seemed to fix it. Phew!
