Introductory transatlantic fares of under £150 will be on offer when a low-cost carrier begins new long-haul services from the UK next summer.
From the beginning of July 2014, budget carrier Norwegian is to fly from Gatwick to New York, Los Angeles and Fort Lauderdale in Florida.
Starting on July 3, the thrice-weekly services to New York will have an introductory one-way fare of £149, while the Los Angeles service, starting on July 2, will be twice a week with an introductory fare of £199 one way.
The Fort Lauderdale flights will start on July 4, with the twice-weekly service starting with an introductory fare of £179 one way.
The US flights will be on the new Boeing 787 Dreamliner plane
Norwegian also announced it would be starting five new European services from Gatwick next year - Budapest, Cyprus, Sicily, Santorini and Corfu.
Norwegian's chief executive Bjorn Kjos (KJOS) said: "There's great demand for high-quality flights at a low fare between the UK and the US, particularly to and from Gatwick.
"We are looking forward to welcoming many new customers on board our brand new aircraft."
Gatwick chief executive Stewart Wingate said: "This is one of the most exciting route developments since Gatwick's change of ownership four years ago."
