Hi Biggless. Thanks, yes there is a Fast Track for connections but it is truly poorly placed all the way at the other end so you end up walking past numerous security lines, before reaching Fast Track. There is usually a guard there but often they have not asked to see my boarding pass. At T5 fast track works really well if you originate from Heathrow (checkin at T5) with proper checks, and lounge is right after the Fast Track Security Line so great, but for us connecting passengers, a real disaster!!
