People pi$$ and moan about connections at LHR, but I read that the bus to/from T5 to T3 no longer makes you go through security again. Is this correct? If so, that takes away a big deterrent to connecting to/from BA-AA at LHR. I also read today in American Way that Sept. 1st AA/BA started a connections bus in ORD to the International Terminal so you don't have to take the train and re-clear security to make a BA connection. Sounds like they are trying to make the process a little more palatable and more user friendly. Does anyone have anymore insight or have you used any of the services?
