A strike by Norwegian pilots has grounded the airline's domestic operation in Norway, Sweden and Denmark for a second day.
Some 650 pilots went on strike yesterday in a dispute over pay, leaving around 35,000 passengers unable to fly.
The airline has admitted that another 35,000 passengers will be affected by the industrial action today. All domestic Norway flights are again cancelled, and only a handful will take-off in Sweden and Denmark.
Norwegian CEO Bjorn Kjos said: "We cannot afford to have a strike forever. And we know that unions have gone on strike until companies crash and burn before."
However, he added: "We are not going bankrupt tomorrow or the day after or the day after."
The pilots are striking in order to achieve a collective labour agreement with Norwegian's parent company, instead of its local subsidiaries, and for the same employment terms to be put in place across Norway, Sweden and Denmark.
They went on strike after talks broke down on Saturday, but those on strike increased from 70 to 650 yesterday.
Norwegian said passengers affected by cancellations can call its customer service centre at +47 21 49 21 49.
Earlier this week, the carrier announced it will add a third weekly service between London Gatwick and Los Angeles next winter (see news, March 2).
