I’ve commuted for 9 out of 10 years of my airline career. I am currently on my second LW metal frame bag. It is getting to be about time to replace my current one though. The biggest issue I have seen on both bags is the zippers. Supposedly the newer(more expensive) LW has fixed the problem. Occasionally do need to tighten screws. Takes 5 minutes once or twice a year. I know the stealth bags get a lot of hate but I like them.
