Got 10 years out of bag #1, only sent it back once for a "tune up". Frame was straightened out, zippers replaces, and screws that came out replaced, etc. Was like a new bag. Commuted the whole time with it. Albeit, not on RJ's. Just occasional DH's and not much exposure.

Almost 7 years on bag #2, still going strong. Same, no RJ commuting and just sporadic RJ exposure. Bag 2 is the "suiter" with the additional pocket on the flap. If I need to, I can easily get 10-12 days worth in it if I need to. Or, in the winter I can easily carry the overnight coat as well as a whole slew of other things with no additional bag required. But it will be heavy.

Although, bag #1 was purchased in 2000 when it was PNS and the bag was better built IMO. Better/stouter nylon, etc but the kick plate was weak and separated on the 90 degree bend where it guards the bottom of the bag.

Bag #2, has a better kick plate with a guard on it at the 90 degree bend and is showing ZERO signs of fail.

I haven't looked at the plastic frame bag lately. But it USED to be the weak spot was where the handle mounted in the top frame. It wouldn't take long before that area of frame weakened/fatigued where the telescoping handle mounted.

Granted, that WAS when EVERYONE had a flight bag and that was the spot that took the most flex/stress. Especially when going up and down curbs, etc.

Seems I remember PNS having a longer warranty period than LW. But it is nice to call LW, have a loaner sent to you in a box that you place your bag in and send it back for work if needed. Then repeat to get your bag back.
