Where is the F Concourse?
 

If you are told to go to an office at the F Concourse, would you expect it to be inside or outside of security?

Is the office "U"? :p

Every concourse is an F the TSA concourse!

Which airport? At Atlanta for instance, all the concourses are within the sterile area. There are parts of our F concourse that might not be considered to be in the sterile area, but those might actually be considered part of the International Terminal rather than the concourse.

Where is the F Concourse?
 

I'd start looking after the E Concourse, and turn around when I got to the G Concourse.

I'd ask the person who told me to go to the F concourse…

Hey! There is no concourse G. Only they have T, A, B, C, D, E & F.

You assume Atlanta. The OP didn't specify which airport.

He assumes correctly. I got the approval email for GE on Weds and made an appointment for my interview. Turns out that the first appointment here in San Antonio was June 6th. So I made that but I figured that I would try to do a walk in as well. Got the ATL yesterday for a flight home, cleared security on the domestic side, took the train to the F concourse only to find out that the interview location is outside of security. I didn't have time to do the interview and clear security a second time so I just left feeling very pissed at my federal government.

Because OP went to the wrong place, he's angry?

If he had called or even posted on FT the specific airport and the location which he was seeking, either CBP over the phone or any # of people on FT would have given him the information.

Yep, I'm angry. I'm angry because the government was able to take my money in a timely fashion but not able to have an appointment less than four months away.
I'm angry that when I went by SAT looking for a walk in I found out that all of the agents that deal with GE leave at 4pm.
I'm also angry that they say that the office is in the concourse when it isn't.
"airline passengers had to pass through the security checkpoints before being allowed in the concourse"

Yes, this is one. They have entire concourse T, A, B, C, D, E & F. He didn't telling me for which airport is that.
