A major revamp of all of the LHR BA lounges including a new CCR and apparently a separate entrance so that F and GGL passengers no longer need to walk through GF.
First lounge to be refurbished at LHR will be the arrivals lounge.
Perhaps unfortunately, it sounds like those involved in the design of the JFK Chelsea lounge are going to be leading this. Hopefully they have realised how a sink works by now.
