London will become the first European city served by US budget airline JetBlue.
JetBlue will begin flying from New York and Boston to London daily from 2021.
The carrier officially announced the news on Wednesday, hinting it would add other European destinations soon after.
In a statement, JetBlue COO Joanna Geraghty said: “London is the largest metro area JetBlue doesn’t yet serve from both Boston and New York, and we could not be more thrilled to be changing that in the years ahead.
“The fares being charged today by airlines on these routes, specifically on the premium end, are enough to make you blush.”
More than three-quarters of transatlantic flights are operated by airlines from the three main alliances – Oneworld, SkyTeam and Star Alliance.
Airline industry analysts predicted JetBlue’s decision to enter the transatlantic market since the airline placed an order for 30 next-generation Airbus A321 jets in 2016.
The long-range version of the A321 will be equipped with an updated version of the Mint business class that features both flatbed seats and enclosed suites.
Due to the extraordinarily high costs required to obtain landing rights at Heathrow, it is more likely that carrier will select Gatwick Airport to serve.
JetBlue currently has more than 1,000 flights per day, flying from the US to the Caribbean, Central America and northern South America.
