I do not know AMS very well. I was going through security in the area above *A check-in (SK, LH, TP, LO, ...). There were no signs of *A fast track anywhere, despite my boarding pass saying that it is available. The agents in the check-in area looked at me as if I was coming from another planet when I asked for fast track access. Then they said that I have to go to the big line, and perhaps once I am on the first floor I can find something. I was appalled at this creative concept of fast track, which works only when there is no long lines (so exactly when it is not needed).
Once on the first floor there was no signs of a fast track for star alliance elites, only for SkyPriority. I did not try my chances with the dragon at the entrance there - so maybe this also works for *G, but I do not know. At that point, after 2h in the line, the time saving was only about 10-20 minutes, and I was completely resigned and obedient. Not in a mood for a dispute.
