Well I finally signed up for TSA/Precheck the other day. $85 for 5 years seemed legit.
Basically had to fill out an online application and then schedule an 'in person' interview.
The application included asking for my maiden name as well as any 'aliases' I'd used before. So of course I felt obligated to share both my maiden name AND my OLD name. That brought back old feelings of dysphoria hah....and I wondered if I really even needed to do that (my BC does have my proper / maiden name on it nowadays).
I went in for the interview and it was really no big deal. They took fingerprints and the guy had me verify everything on the screen. If he saw or thought anything about the names/aliases screen, he didn't say it....and I was thankful.
Was way easier than I thought it would be, yay! Now I get to bypass the big lines at the airport

Will come in handy for my FFS consult in San Fran (and prob for the actual surgery flights too).
