Well Jim, at this point we'll just have to see. I've experienced not a whisper of difficulty so far.

As far as baggage handling rules go, my bike could be considered sports equipment, which has worked the one time TSA became even remotely curious. Also, there's the Transformers argument. Is a Transformer really a car when it's a robot? Well, I have a bike that transforms into rolling luggage... that got me onto a bus one time.

The truth is, it seldom comes up. They take it and tag it, without a blink of an eye. Or, sometimes they say "cool bike!". That's it.

I don't remove the seatpost because... I don't have to.
