Cathay 38 J on the A359
Singapore 42J
Aer Lingus 30J (x2?)
Virgin 16J on an A35K and 32 on an A333.
BA often 8 rows of club, so 16J
Plus KLM?
Plus Lufthansa?

So we are already at 292. Then add on status holders…. It is going to need to be a flipping big lounge I suspect multiple lounges are inevitable, with some carriers using contract lounges.
