Norwegian Air and JetBlue Airways are planning to form a partnership that will allow flyers to book flights on each other's airline, with an aim to provide seamless travel between the U.S and Europe. The planned start for this partnership is sometime in mid-2020 if both airlines commit to an agreement.

Norwegian Air shook up the industry by introducing low-cost flights between Europe and a host of North American, Latin American and Caribbean cities. However, the airline has lacked a domestic U.S. partner. If the partnership goes through, passengers will be able to enjoy low fares via a single booking for flights between Europe and the United States, the Caribbean and Latin America.

Under the proposed partnership, a traveler would be able to take a domestic flight to New York's JFK or other US airports where Norwegian Air serves and then connect on a Norwegian Air flight to Europe, all on a single booking. Travelers would be able to check luggage from their origin airport all the way to their final destination, even if the connecting leg is via the other carrier.

JetBlue's has bases at New York's JFK, Boston and Fort Lauderdale, and just from these three bases, Norwegian Air offers more than 20 nonstop routes to Europe. To start, the partnership will not offer reciprocal frequent flyer benefits, but that could change in the future.

According to Norwegian Air, it expects the partnership to launch early next summer. With two low-cost airlines forming an alliance, this should be good news for flyers who want to enjoy a seamless connection between Europe and the United States, Latin American and the Caribbean. It could also force American, Delta and United to offer more competitive prices between the United States and Europe.
