The carrier confirmed to TTG it would not restart its JFK service in 2025.
A spokesperson said it had made the decision “to better align with anticipated demand”.
It had earlier moved both JFK and Boston Gatwick routes to a summer-only service.
The Gatwick-New York route has been hotly competitive, with Delta reappearing in summer 2023 after an absence of 15 years, adding to flights from JetBlue, British Airways and Norse Atlantic Airways.
