I never got as far as answering the questions, "it" didn't even ask for me to verify flight info. It spit out an "X" ticket almost immediately after I did my fingerprinting on the glass. When I went to the next available agent, I was escorted to the "special room", after 5 minutes an agent processed my entry. I asked what had occurred and he thought it was fingerprint related. After leaving the "special room", I had to hand my blue slip (which I had filled out, earlier, just in case) to the agent at the door.
A day or two later I got an email from GE, asking me to describe my problem, I guess a glitch occurred and they wanted to find out why and make corrections. My one (and hopefully only) "X" in lots of intl. trips.
Ah, okay . . . the "malfunction X" instead of the "random/extra screening X".
