Effective September 1 the New York JFK lounge will have 35% more space because they’re converting the attached B concourse Admirals club to become part of the Flagship lounge. This adds 7000 square feet to the existing 19,541 square foot Flagship lounge footprint.
That means the only Admirals Club at JFK will be the C concourse lounge. However most domestic flights — which is what most Admirals Club passengers are flying — depart out of the satellite C concourse and as a result the B club which was renovated last summer doesn’t ever seem busy.
