The airline warns it will again seek heavy financial compensation against Avinor if traffic chaos results from industrial conflict.

"The statements from flight control officers after the Avinor board meeting Wednesday night greatly worries us. The controllers made it clear then that they cannot guarantee stable service in the future," SAS Braathens boss Petter Jansen told Aftenposten.

"On behalf of ourselves and our passengers we therefore now want a declaration from Avinor that we can count on traffic leading up to Christmas being run according to our schedules," Jansen said.

SAS Braathens alone lost NOK 15 million (USD 2.4 million) when flight controllers collectively called in sick after Avinor decided in September to scrap the current control headquarters in Røyken, outside of Oslo. Jansen is now frightened this could happen again, and hit crucial pre-Christmas traffic.

The National Association of Airlines also demands order from Avinor. The group is calculating the cost of damages that it will demand from the September traffic collapse.
