It amazes me that people freak out when they see "Muslim-looking" people on flights. I may not be flying often enough, but I am flying both in the USA and International, and I have never seen this happening. (Maybe someone was freaking out quietly and I have not noticed.) Is this your experience, or are you extrapolating from what you have read about it?
