I do a fair amount of air travel and I swear by these bags. I have had mine for over 4 years and it is still going strong (wheels and all).

My wife had one too, but Delta slashed (literally) the top off the bag over the holidays. It was checked at the gate and somewhere between there and my wife's arrival Delta ripped through most of the top of the bag. The replacement was about 3x the size and not nearly the quality...

I like these bags chiefly because they fit in the overhead compartment and can hold 2-3 suits no problem. I ordered this bag the day she landed for delivery to her destination. Amazon, as usual, came through with a fast delivery!
