Against the grain, but my recent early morning visit to the T3 BA lounge was very quiet and pleasant, particularly after I had just left a very crowded CX F lounge, and then swung-by another very crowded AA Flagship lounge. If there is a separate CCR area to come then that could only be a positive.

Will be interesting to see if BA give access to GGL pax not in F for these potential new areas (T3 +/- T5B) or if they default to more of an IAD/DXB/BOS etc. CCDR type of access restriction.
