This may surprise you but at Brookstone they actually have pretty good luggage. I actually just picked up a floor model rollaboard that was sitting in our back room for $50. Can't remember if it's 21 or 22 inches but it has tons of innovative pockets and lots of room, plus a fold out suiter for your shirts and a fold up toiletry kit. It's black "ballistic" nylon. Not sure if it would be considered "airline pilot capable" but working there for 2 years I've come to see which products are good and which are bad, and our luggage is probably some of the best stuff we sell.
Current price new I think is $125 or so, 30 day return period with receipt and in like-new contition. One year warranty for manufacturing defects only, must have receipt. No receipt, u get nothing.
By the way, Brookstone as a company has gone down hill and I can't take the nasty customers anymore so I handed in my notice the other day.
