food and drink selection in LGA was good, too. Several types of seating areas, lots of outlets. never been to United club/JFK lounge.
UA Club JFK is a poor excuse for a club. It's old and tired-looking, and is generally crowded. No showers, the bathrooms aren't much better than standard airport offerings, poor selection of refreshments, worn upholstery, etc. Best one I've been to is the big one at EWR, although the renovated on in LAX comes pretty close.
Best club I've personally been to in JFK is DL SkyClub T4.
