The Jet Blue lounges are going to be called Bluehouse in JFK Terminal 5. It will be available to Mint passengers to only Europe, Jet Blue Mosaic 4 and 1 guest, Jet Blue $499 fee cardholders and 1 guest. Guests are $39 each.
If you want to see more photos of the lounge check OMAAT’s article. That is all but I am happy Jet Blue is starting on this.
