Primera Air is to open a new base at London Stansted and start direct flights to New York and Boston Logan next year.
From April 2018, the airline will offer daily services to New York’s Newark Airport and four a week to Boston Logan Airport from May.
Primera Air will announce another trans-Atlantic route from Stansted by the end of summer 2017.
Flights will be operated by new Airbus A321NEO aircraft and include a choice of two cabins, full-service premium and low-fare economy, free Wi-Fi and on-board charging points.
Andri Ingolfsson, Primera Air president, said: “We are very proud to announce our new base at London Stansted and routes to the USA.
“With our brand new Airbus A321NEO aircraft, we are opening routes previously traditionally served only by wide-body aircraft.
“With unmatched efficiency of these new-generation aircraft, we will be able to offer unprecedented prices to our passengers from London Stansted to the USA.”
The Danish airline will be the first airline for nine years to fly scheduled services to the USA from Stansted.
Andrew Cowan, London Stansted chief executive, said: “We’re thrilled Primera Air has chosen London Stansted as its UK base for these exciting and innovative new long-haul services to the USA.
“We know from our customers that there is enormous demand for flights to New York and Boston from London and the east of England, so the arrival of Primera Air is fantastic news for both business and leisure passengers wanting great value, excellent service and the convenience of flying transatlantic from their local airport.
“The welcome arrival of Primera Air to Stansted offers passengers even more choice and provides great new transatlantic connections to New York and Boston – both of which are important destinations for businesses in our catchment.
“I’m sure these new services will prove to be really popular and we look forward to working with Primera Air to add more routes in the future.”
