I just got off the plane in Atlanta coming from LA. Had another flight before that.
I am in full girl mode, wearing female clothing, makeup, blonde wig, padding, bra and breast forms. I look nothing like my drivers license.
Had no problems what so ever!
TSA: "ID please, Look at the camera, Have a nice day.
Security, carryon with a ton of makeup included liquids, large purse with more girl stuff.
2 large suitcases with enough woman's clothes for a whole transgender convention. Another set of breast forms.
Nothing but smiles and friendly people.
I noticed No reactions from anyone all day. Interacted with many along the way including airport and airline personnel and fellow travelers including a couple of teenage voters girls who referred to me to eachother as "Her" and "She".
But the main point is, with regards to TSA, Checkin agents, bag security, and airline personnel, it is really not a problem.
