There's a lot to fret about traveling through T3 but, IMO, the BA lounges aren't part of it at all. TBH, the addition of a fast track line for security at connections has helped a great deal anyway and if they could stop the bus trips to stands it would be just dandy for me. If I'm not looking at a trip with access to the CCR the lounges in T3 are far better IMO just because of the P&Q. This may change when they play musical chairs after opening the new new terminal, but for now I rather like being in a Galleries F lounge with 15 other people
