Knowing the management, they are waiting to see if SAS fail, and then they know even more 737 rated individuals will be on the market desperate to accept anything, or use that as a stick to use against hopefuls.
Several guys have recently turned down their 70% offers to go to Etihad or others with newer 737s. Others who were originally offered permanent 70% Jet2 contracts but then told they were being changed to Zenon contracts (i.e. not permanent) have also turned down Jet2.
As far as I know, quite a few Zenon 757 guys have not been offered contracts (permanent or Zenon), despite being told last year that they would normally be offered permanent contracts as a sweetener.
