The CS agent on the phone assured me there'd be no security issues since "my bags were checked through." Long story short: Two passport control queues, then a LONG queue for liquids/electronics out of bags, X ray, the works. No help from surly LHR staff, which always shocks me a little given how lovely UK residents are in general. Came within minutes of missing my connection. I wonder why so many airlines can't seem to offer correct information on connections in larger airports - had a similar experience recently on Alitalia in CDG. I'm really starting to consider 180 minutes the minimum for these huge facilities once you factor in delays and security queues.
