This bag is big. If you fill it up (without expanding it) its thicker than advertised. I was a little worried about it but everyone still let me take it on as a carry-on even though it was technically bigger than carry-on restrictions. I took it on 4 planes on a trip to hawaii for 6 days and it held everything I needed including a suit.
The extendable handle is well built and i like the separate compartments. I even had a flight attendant ask me where I got it from.
