Looks like SQ flying out of JFK will now use the "new" Wingtips Lounge in T4 - which is the recently renovated Swiss lounge as per TPG. Swiss moved from T4 to T1 and so had a newly renovated empty lounge in T4 that Wingtips moved into. Wingtips is a Priority Pass lounge to will be a mixed bag.
It looks good but still bummed that there is no dedicated SQ presence for flying J/I out of JFK.
