I have a constant issue with the Fast Track queue in North Security when going through Flight Connection at T5A. The FT queue at the BP and passport control is marked very clearly (at the right hand side of the hall) but I could never tell how to get to the proper queue in North Security. It seems that the escalators take you to the regular queue and that the FT is at the left side of North Security. Is it so? And how does one get there after clearing FC?
