The security guards are still on strike and if no progress is made in the negociation today, they will call for 450 new employees to join the strike on Wednesday, among them 50 will be for Gardemoen. It should worsen the situation there even if today's it is not so bad as many have cancelled their flights.
It is no confirmed information on what will happen later and with which timeline. However, two more organizations may join the strike from the night of Friday to Saturday: the maintenance mechinals and the air controllers. This may significantly impact air traffic in Norway.
