I can’t count how many times I have been through airport security, worldwide, including dozens of times with my husband. I’m a white “girl next door” type. My husband is harder to peg (he has been “read” as Chinese, Okinawan, Thai, Indian, Arab and more, although he is from Mexico). Whenever we travel we have come to expect delays for him in security, while I regularly breeze through. It just doesn’t feel random.
