The real question is why does JFK have one? Happens to be one of the worse UA Clubs I've been to. LAX T8 downstairs one is under construction now, but it's starting to look really nice. But nothing can beat the JFK Delta Sky Club, which was very conveniently situated right next to the El Al gate at JFK T4. While I hate their planes, I loved the club. Guess the reverse applies for UA.
