I've done a lot of traveling, and have gone through a lot of luggage since the early 80's.  And I miss the days of no baggage fees, and having to be so careful of the size of the luggage to not get nailed with another fee when they say "Sorry, that won't fit."  Since this one is specifically the size allowed for carryon for most carrier airframes (other than the little prop hoppers probably) that problem should be minimized.

This unit is VERY well constructed.  No loose threads hanging out, zippers all feel nice and solid, and the pulls work well and the teeth mesh perfectly.  Looks great, and the expandable/collapsable handle works well, lock and all, and feels quite solid when extended.  The wheels pivot well and roll well when you're pulling it behind you, but the thing I don't like about them is that it doesn't roll well when tilted and PUSHED rather than pulled.  Sometimes as I'm going it's easier to push a piece of luggage in front of me depending on traffic flow, and this one just doesn't do that at all.  One of the wheels will stay in the right position to be pushed, but the other won't line up in that direction, and points off, making this thing roll in random directions.  So while the wheels work quite well, it's only when pulled behind as designed...

Other than that this is one of the better pieces of luggage I've had as far as sturdiness and flexibility.  the carry handle is very thick and well made, the metal bands thicker than most I've seen in this size, and double riveted to the bag itself.

I took this on a trip this week, and had no problems with it fitting in the compartments on a Delta jet, it fit both ways, shoved in wheels first so it was "longest" way to protrude, as well as pushing in sideways when there were not many people on the return flight.  Held up great, no scuffs, and the little plastic bag that it comes with for toothpaste and such was enormously helpful going through customs.  As was the front zippered section, which is where I carried both my iPad and my son's iPad, so they were quickly and easily removed for the security checkpoints.
