Hmm, I know a few people at the Port Authority. I'll have to pry them for info
Seriously, though, I never liked the A lounge. Small and cramped.
@SEA1K4EVR - there is another UC at LGA outside the C concourse. The A concourse club is the legacy President's Club and the C concourse club is the legacy RCC. It is much bigger and brighter than the A lounge. Could use a refresh, but a decent enough club. Also, they have a mini-fridge with yogurt available all day!
EDIT: @jmr50 - they are DEFINITELY keeping the legacy RCC. Rumor mill says they want to expand it so the entrance is inside security. I could imagine an entrance like the Newark Terminal A setup where the RCC entrance is literally right next to security.
