Can someone advise how you get from T5 to T4 (ie for the bulk of BA long haul to short haul connections at the momet).
Read someone saying you wait 15 minutes for the Heathrow Express to depart, over to Central Area, cross the platform, wait 15 minutes for the train to T4 to depart - it took them 90 minutes overall. Can't believe that's all that's available. It must blow the Minimum Connecting Time. Even Piccadilly Line via Hatton Cross would be quicker.
