Do you guys never carry any tools for your bikes ( allen keys, wrench/spanner etc. ) that TSA would object to ?
I don't think I would manage to go without at least some check-in baggage.

Last year when I flew to spokane, I cycled past a cutting that was being blasted for a replacement bridge span.
TSA ripped my Brompton hard case to pieces - removing ALL the lining.
The bike looked like they had got frustrated trying to work out how to fold it after their swabbing.
The hard case was not tightly closed - so once the united handlers threw it around a few times, it has never properly latched shut. :-(

Fortunately last week - on the same trip the Brompton was unmolested and the case took on no further damage.
