JetBlue and Norwegian Air have signed a letter of intent to interline. Travelers will be able to combine connecting flights across the two carriers when booking on their respective websites and global distribution systems by summer 2020. The partnership will connect JetBlue flights to Norwegian's 20 nonstop transatlantic routes out of Boston; Fort Lauderdale, Fla.; and New York's John F. Kennedy International airports. "The partnership will provide travelers throughout the U.S., Caribbean and Latin America with more affordable fares to Europe and vice versa, and … it will offer seamless connections with two of the most awarded low-cost airlines in the world," according to Norwegian CFO and acting CEO Geir Karlsen.
