Scandinavia's SAS is to challenge budget carrier Norwegian on the transatlantic route to Los Angeles from Copenhagen next year, by transferring its current service from Stockholm.

It says it will "relocate" its services on the Stockholm-Los Angeles route to the Danish capital from 13 January 2020.

The Star Alliance carrier will increase the connection to a daily frequency starting in March, ahead of the summer season.

"The timetable is attractive, and thanks to the economies of scale we can achieve in fully utilising our fleet, we are in a position to provide a daily service from Copenhagen,” says SAS executive vice-president, commercial, Karl Sandlund.

Passengers already booked on the Stockholm-Los Angeles service will be rebooked via the new flight.

SAS currently uses Airbus A330-300s on the Los Angeles route.

Norwegian already operates on the Copenhagen-Los Angeles sector, with daily Boeing 787 services.

SAS says the US gateway is "one of the most in-demand intercontinental routes" from the Danish capital.

"We continuously assess our offering in order to optimise our network for our travellers,” says Sandlund.

SAS is to start taking delivery of Airbus A350-900s from January, which will be deployed on some US routes from Copenhagen including Chicago, New York and San Francisco.
