One of my Pocket Rockets got a slightly bent seat mast tab while the bike was packed in a suitcase from Chicago to London. Found the damage while unpacking in my London hotel room.
Crush protector was in place and everything was properly situated. How it happened is a mystery. I wonder if the case had been opened and played with by TSA or their UK counterpart, but if it was, no one left a note, and back then, they typically would. I suppose if everything were not arranged back in the way I packed it, something like this could happen, but I wasn't paying as much attention when I was unpacking it because I hadn't seen the damage yet. That's what's so weird.
I always have detailed photos about how the bike goes into the case, along with my name, phone # & contact info, taped to the inside cover of the suitcase in a sheet protector as a friendly gesture toward those inspecting. I go out of my way to make sure whoever is inspecting realizes that as far as stuffing the bike back in the case, there's only one way it works without damaging the contents.
Back in my London hotel room, I was able to straighten out that tab very carefully and resume my trip as planned, but that experience made me much more cautious about how I expose the frame, and how I pack around it. No guarantees.
