Whoa, I'd never heard of a bike bag. It's still oversized, though. What do you guys think about how easy it'd be to tetris a bike into a cardboard box small enough that it wouldn't be considered oversized by the airlines? Guess I'd have to know the outsize of their less-than-oversized dimensions, eh? Hmmm...time to call up KLM.
I'm moving to Barcelona at the end of November and this is a timely discussion.
