The service will allow easyJet passengers to connect with other easyJet flights through Gatwick Airport, south of London.
The connectivity has been made possible by a partnership with comparison site Dohop, whose platform will enable Easyjet customers to book connections and forward flights.
"Worldwide by Easyjet' makes the low-fare airline the first of its kind to offer global connections with other companies".
Passengers taking connecting flights via London Gatwick - like those travelling from Aberdeen to NY - will be able to book the entire trip on easyJet's website in one booking.
"We already see a large number of passengers making connections between Norwegian's own long-haul and short-haul networks and we welcome initiatives like Worldwide by easyJet that give customers even more opportunities for affordable transfers between flights".
As well as adding partners at Gatwick Airport easyJet plans to expands to other key easyJet airports in Europe such as Milan Malpensa, Geneva, Amsterdam, Paris Charles De Gaulle and Barcelona.
Guy Stephenson, Chief Commercial Officer, Gatwick Airport, said: "GatwickConnects lets passengers seamlessly self-connect between different airlines at Gatwick at the touch of the button. easyJet is our biggest airline and by partnering with GatwickConnects, easyJet passengers can easily and quickly self-connect with other flights in Gatwick's diverse network of flights including our 60 long haul routes".
Bookings will include the GatwickConnects service, meaning passengers' checked luggage will be transferred to their second flight, and if they miss their connection they will be given a seat on the next available flight free of charge. You'll still need to transfer your own baggage between connecting flights.
EasyJet insisted the scheme will not impact on its punctuality or operating model.
Easyjet will also sell stand-alone tickets on behalf of partner airlines, allowing customers to book flights without connections. Future partner airlines will benefit from exposure to Easyjet's 360 million website visitors.
Norwegian is partnering with easyJet on the new "Worldwide by easyJet" platform, allowing passengers to connect a Norwegian long-haul flight with an easyJet short-haul flight in one single booking.

"By opening this new market segment this now means that easyJet can access a greater range of passengers flying across Europe".
The new service is called Worldwide by EasyJet, and will use GatwickConnects to help passengers jump from one flight to another at the airport.
