Norwegian will double its services from London Gatwick to both New York JFK and Los Angeles next summer.
The carrier will increase the number of JFK flights from three to six-weekly on May 2, while the LAX service will be upped from two to four-times weekly on May 4.
Norwegian will also increase its Oslo to Los Angeles route from once to twice weekly on April 1 and its Stockholm to Oakland route from twice to three-times weekly on March 30.
However, the airline is also reducing service on six other routes in summer 2015, reports airlineroute.net.
These reductions, based on Norwegian's current summer 2014 service, are as follows:
- From March 29, the Stockholm to Bangkok route will be reduced from three-times to twice weekly
- From March 31, the LGW to Fort Lauderdale service will fall from twice to once weekly, and the Oslo to Oakland route from thrice to twice weekly
- From April 2, the Copenhagen to Fort Lauderdale route will drop from thrice to twice weekly, and the Oslo to Orlando service from twice to once weekly
- From April 4, Copenhagen to Bangkok will fall from twice weekly this winter to once weekly next summer.
Earlier this summer, Norwegian vowed to put an end to "unreasonably high" transatlantic air fares as it celebrated the launch of its first flights between London Gatwick and the US (see news, July 4).
