To sum it up-
18 months ago your bag you bought in 2003 "let go" and isnt worth fixing (again/anymore) and Tumi wont replace it for free.
Your pisst, I get it I would be too, but you did get a reasonable lifespan out of your purchase.
Tom Binh is basically saying UP FRONT that nothing lasts forever.
I wouldnt bet on everything that happens with every client good or bad getting written down for you to personally review, and I think if you believe Ton Binh would just swap it out with a new bag - based on their own statements up front you may be in for big disappointment if you use it hard for 10 years.
They are telling you up front your bag has a finite life.
Redd Oxx - The airboss simply holds more that the aeronaught, not as pretty though, I love the zippers on the Tom Binh stuff and the Tom Binh strap puts the claw on the shelf. In Red Oxxs line if you want backpack straps you get a skytrain.
