Flagship Lounges sell Single Visit Pass for $150 or $15,000 AA miles regardless of elite status. It was a very convenient option for dinner before heading home from a late night flight. Since there is no Flagship Lounge in JFK anymore, is it still possible to buy a Single Visit Pass at Greenwich Lounge (old Flagship Lounge)? Anyone tried? If not, is there a way for EXPs to get access to a nice lounge (paid or free) for domestic paid first class ticket?

Many thanks,
