Scandinavian Airlines says some 50 flights have been canceled Monday to and from Denmark after members of a Danish cabin crew union walked out to protest the carrier's plan to transfer employees to a domestic airline acquired by SAS.

Group spokesman Henrik Edstrom said the action, involving flights within Scandinavia, brings the number of cancellations to more than 100 since the pilots began their protest on Friday.

Meanwhile in Norway, flights by a subsidiary of low-cost airline Norwegian Air Shuttle — Norwegian Air Norway — were partly disrupted after pilots continued a walkout begun on Saturday, causing the company's share price to crash 5 percent in Oslo.

Officials at Norwegian did not immediately return calls or answer emails seeking more details.

Talks to solve both disputes are continuing.
