As a GS, you can use the F class security line even though you will be relegated to coach on Ted. You don't need a pass from check in or anything, just show the F class security ID checkers your GS card if the give you trouble.
The last few times I've done this, the F line has less than half a dozen people in it and has been orders of magnitude shorter than the regular line. Oh, and I also talked to Ivanna Trump.
