Forget the bag tags they have for you from the airlines. I swear I've put one of those on my bag and watched it fall off as they tossed my bag like an old sack of potatoes on to the conveyor belt.
These tags are made from Tyvek which is almost indestructable due to it's thousands of fine plastic fibers in random patterns making it nearly impossible to tear. The best way I could describe it is it's like a thousand little Chuck Norris's clinging together, unwavering in their awesomeness!
So this tag won't fail, and it has a snazzy Air Mail design to boot... so you'll have that going for you, which is nice.
