My knowledge of the deal offered to ex KLMuk pilots is as follows:
1) Pilots over age 46 were not offered an opportunity to apply (age discrimination);
2) The deal included an option to transfer to Buzz, which KLM were at the time secretly selling off to Ryanair (an option KLM knew ex KLMuk'ers would never have the chance to exercise);
3) The deal called for compulsory demotion of F100 captains who would never have sufficient seniority in KLM to get back to the LHS of their own type and never have enough years left before retirement to make up the earnings lost by demotion.
If the reality was that the deal was unmissable, 190 pilots must have been asleep at the time.
