Well, I am now a "Known Traveler", as I know I said here I was applying for it. The entire process took about three weeks. First was applying on line. Took maybe 5 minutes, which included setting up an appointment at a local office about two weeks out. Second was the "interview" which only took about 5 minutes. It was in a nondescript office building in west Omaha, not very well marked, literally an office within an office within an office, with things like "TSA Pre Check" written in marker on paper towel and scotch taped to the doors and such. Since I had the appointment I was called almost immediately. There were maybe 15 or so others waiting and I was one of the first to be called. I was fingerprinted using a finger scanner. No ink. The rest of the interview was interactive with a screen in front of me and in front of the interviewer. Usual questions about length of residence, any criminal history. I had to bring a copy of my birth certificate to prove that I am alive, of course and supporting identification. The only odd point was that of aliases. "Are you known by any aliases?" I said I had a nickname, two actually, so I have three names listed, my full formal name, a common shortened nickname of that, and the nickname I use informally. The interviewer said it was NBD. Then my CC was swiped for the $85 charge, which the interviewer reminded me was nonrefundable. She said I would be informed by mail shortly but I could check the web site in a few days if I wanted. Today (actually yesterday) I got the congratulatory letter and my known traveler ID. It's a seemingly random string. I have not used it yet, but I'm going to try to add it to a plane reservation (not to LV) I have next week. That's about it.
