Martin From BeltedGirls 2015:
"I do fly occasionally for work and vacations, and I fly belted. TSA is hit or miss depending on the agent on duty but Iβve havenβt much problems with this. Once I had to unbutton my fly and fold my waistband down so they could see the top of the belt.
The TSA agents will stop you, it's inevitable, and most often they will bring over an appropriately-gendered supervisor. If not, ask for one. What I then do is show the supervisor a printed copy of that web page. Once, the supervisor wanted to see the belt so I unzipped my fly and she saw where the waist and crotch parts meet with the big lock on front and stopped me as she didn't need to see any more. A belted woman is not what they are looking for."
I think we should avoid disturbing the TSA in their work and try to fly without the chastity belt on. Goes great that it be removed before the security check on any toilet at the airport and put on again when you passed.
