I was at the AY lounge in ARN 3 months ago, and they have a separate "Platinum" (AY's Emerald level) section in this lounge which is accesed with a code. This was quite late in the evening with only one BA A319 and one AY EMB-170 left to depart that day. I saw AT LEAST 10 different people go into the Platinum Lounge (and I can't imagine that most of them were BA Golds), so I have to seriously doubt that AY has fewer than 100 Emeralds.
