With the membership that comes with the card, you'll be able to get into any of the domestic or international lounges (as well as some select partner lounges) if you have a boarding pass for same-day travel on American or its partner airlines (including Oneworld airlines and most JetBlue flights).

In 2026, the ability for JetBlue passengers to use American Airlines (AA) Admirals Club lounges has become more restricted following the dissolution of the "Northeast Alliance." Currently, a standard JetBlue ticket—even in the premium Mint cabin—does not grant automatic access to AA lounges. However, there are specific workarounds: if you are a JetBlue Mosaic 4 member, you may have specific lounge credits or partnerships that allow entry. Furthermore, if you hold a Citi / AAdvantage Executive World Elite Mastercard, you can access the Admirals Club regardless of which airline you are flying that day, including JetBlue. It is also worth noting that JetBlue is in the process of opening its own dedicated lounges at New York (JFK) and Boston (BOS). For most travelers, the most reliable way to access a lounge while flying JetBlue is through a Priority Pass membership or by using a premium credit card like the Amex Platinum, which grants access to Centurion Lounges. Always check the latest reciprocity agreements in the JetBlue app, as airline partnerships are frequently updated based on new codeshare agreements and loyalty program changes.
