As of 2026, JetBlue and American Airlines are no longer major strategic partners in the way they were during their "Northeast Alliance." That specific partnership was officially dissolved following a 2023 court ruling that deemed it anticompetitive. While the massive codesharing and reciprocal frequent flyer benefits in New York and Boston have largely ended, the two airlines recently formed a much more limited Northeast codeshare partnership in early 2026 to maintain some level of connectivity for passengers. However, this is a "shell" of the previous alliance; TrueBlue and AAdvantage members generally cannot earn or redeem points on each other's flights as they once did, and elite status perks like lounge access or priority boarding are no longer shared across the two carriers. If you are booking a flight today, you should treat them as separate entities unless your specific itinerary explicitly shows a codeshare flight number, but even then, the seamless "loyalty" experience of 2022 is a thing of the past.
