JFK VS CH is good. Infact very good when considered as a business class lounge/lounge for elites.
But when you consider it as a FC/Suites lounge, it's in a whole different ball-park, getting compared with the likes of SQ TPR, LH FCT, CX FC lounges at HKG (AAAHHH....the cabanas!!

) and the QF lounges at SYD! Compared to these FC lounges, it's not up there. Just my 2 cents. Congrats on the redemption OP, and safe travels!
