According to
Aftenposten chaos is expected at OSL for all non-*A airlines as Servisair is understaffed due to holidays and resignations. Apparently Servisair has lost a large contract and will fire 100 people from October. A lot of these people have already left the company, leaving them seriously understaffed.
Norwegian states that they expect Servisair to deliver according to contract. I wonder what Mr. Kjos feels now. Suddenly he is struggling with problems he claims only big large stupid airlines suffer from... ooops...
