They’ve publicly been saying they are retiring it for years now. 6 are already parked. Block hours are down significantly already over the last several months, despite it being the busy summer season. 25 people holding JFK/BOS CA awards had their awards canceled.

https://www.planespotters.net/airline/JetBlue-Airways this shows the parked ones. You can check the tail numbers on flightaware for their last flights. Sounds like there’s an accelerated parking plan for the owned ones, and the leased ones will be returned on schedule with 6 going back next year, the bulk of the rest of the 30 in 24/25, and the last one Q1 2026. I’d bet most won’t be flying by 2025 (speculation on my part). By the end of 2024, there will be 67 220s on property. I do wonder what will fly the shuttle stuff though. The 220 isn’t all that great for 30 minute flights. Spirit’s 319s maybe? Envoy or republic 175s is probably the most likely when the shortage stabilizes if the NEA is still in place.
