OK, I have read a number of threads on both of these JFK lounges; but despite that it is not clear as to which one is preferable and FTers' opinions are welcome.

In my particular case I am traveling F on QF 108 to SYD, and arriving on a domestic AA flight so can easily access the Flagship Lounge in Terminal 8 and the Terraces/F lounge in Terminal 7. I have a 5.5 hour layover which is intentional since I am flying the day before Thanksgiving (call me crazy). I do NOT drink alcohol, so the lounges' alcohol offerings do not matter to me. I do prefer sparkling water and decent lounge food is important along with lounge comfort. I do want to visit both lounges, but since I will be arriving in Terminal 8, once I leave there for terminal 7, I don't really want to return. My inclination is to hang out in the AA Flagship most of the afternoon and then head to Terminal 7 Terraces lounge about 1.5-2 hours before my SYD flight.

With that said, can some of you please provide recommendations. TIA
