Among the other big announcements today, JetBlue intimated that they will be issuing a premium credit card in 2025 which will grant access to the upcoming lounges at JFK and BOS. Presumably this would be in conjunction with Barclay's. Relevant snippet below:
A lounge that's worth the wait
Our first-ever dedicated space to play, work and lounge will land at JFK's T5 in
late 2025 and Boston Logan's Terminal C soon after, with complimentary
access for Mosaic 4 members and a guest, Mint customers on transatlantic
flights, plus those with the soon to be launched premium JetBlue credit card.
An annual pass will be available for purchase. More details to come.
