Denmark and Sweden are bailing out SAS with a 2BN DKK loan guarantee, and a further promise they'll "do what it takes" to get the airline through the crisis. The vast majority of staff have been sent home with up to 30K DKK of their monthly salary paid by the state, the balance by the company.
The Netherlands and France have agreed they'll do what it takes to keep AF/KL afloat, and the German government has done the same with Lufthansa. Apart from Lufty employees going on "kurzarbeit", I don't know the terms.
