I've been through various airports eight times in the last ten weeks, crossed the U.S, the Pacific and the Atlantic, with and without my bike. I haven't come across anyone or anything that I considered rude, annoying or violating. I only got a pat down twice, and both times, they were non-obtrusive and the agent was extremely polite.

The only annoyances were people who did not know of the TSA carry-on regulations, thus holding up the lines.
