Primera Air will begin direct flights five times a week from London Stansted to Washington Dulles airport from August 22.
Flights will be operated on Primera’s new Airbus A321neo and A321LR fleet, which will be in operation in April.
The airline will also increase frequency between Stansted and Toronto from three to five flights a week, it has announced.
“We’ve been planning to add Washington from the beginning of the transatlantic flight project,” said president and owner Andri Már Ingólfsson.
“We see a strong demand for this route and we are the first low-cost airline to start operations between both cities, offering people an affordable way of transatlantic travel.”
Ken O’Toole, CEO of Stansted airport, said: “We’ve already seen a very positive response from passengers to Primera’s previous announcement of new services to New York, Boston and Toronto, and the addition of Washington will provide even more choice and connectivity to the east coast of the USA.
“The announcement of Washington Dulles Airport joining Primera Air’s existing long-haul schedule, as well as the increased frequency to Toronto, is a real vote of confidence in Stansted and of the demand for long haul flights to and from London and the East of England.”
Ingólfsson added: “Our booking numbers show that travellers have been waiting for flights to North America. We are very satisfied with the results so far and are adjusting our flight network accordingly.”
Primera Air now hopes to add more services to the USA and add routes to China and India.
As announced previously, Primera Air is opening new bases in Birmingham, Stansted and Paris Charles de Gaulle for flights to New York, Boston and Toronto this April and is introducing new route from the UK to Málaga, Palma de Mallorca, Alicante, Barcelona and Chania.
In the next two years, Primera Air plans to increase its presence on current bases and add new transatlantic routes and bases, as the airline has 20 new Boeing MAX9-ER on order.
