My LW 737 Stealth is over 5.5 years old...had to put Loctite on the bottom screws, take a file to razor-sharp burrs on the skidplate made by sidewalks/concrete steps, I've lost a couple zipper pulls, and the frame slightly bent courtesy of PHL rampers - but its still going strong.
Its WAY overkill for corporate flying, but for an airline job I would never own a different bag.
