For me, it's been hit or miss all depending on what ID I use and where I'm at.

If I'm at an airport that handles alot of military personnel, I'll use my Geneva Conventions ID (CAC). Rarely a second glance, it's quick.

If I'm not, I usually use my passport. This has provided some problems for me. It was issued in 2000 and has been used extensively and it shows. Problem being, some screeners seem to think it's fake. I've had that come up twice now. First, then go over and over it, look at it, look at me, repeat. Then a sup gets called and they do the same thing. So far both have asked me when it was issued to which I state "2000, like it says in the passport". You don't even need a blue light to be able to see the couple holograms that are there. The first time this happened, they asked if I had another ID on me. Nope. I was flying to FRA, that's all they get. It's frustrating, yet kinda entertaining in the same token. Some of these fools are so incompetent, it's scary.
