THanks Petrus and BBB! I can see how to get from North Security to the CCR with no problem looking at my LHR T5 map. What I can't figure out is how I get from arrivals to North Security. Is there a special channel for connections that bypasses immigration? Sorry to be so dense, but I get confused with maps that have more than one level! What I am trying to get a picture of is what happens to me between leaving the plane and arriving at North Security? Sorry to be such a pest, but I am obsessive about knowing exactly where I need to go.
