I made the mistake last year of seeking out the B SkyClub on one of my rate ATL layovers- the Club is simply too crowded and suffers from wear and tear. I promptly went back to the T Gate Club, where my flight was actually leaving from

The SkyClubs I have enjoyed the most in ATL are Concource F, T Gates and C if I remember correctly

Almost all issues with SkyClubs are driven by crowding - however this is the same issue as almost all domestic clubs. No real solution in the current economic climate

I know people give JFK T2 grief, but I think it is fine, bartenders are good, etc
