The algorithm was a free hand to mid-managers, base captains and base managers (for cabin crew) to get rid of people who are not quiet to their liking, so to say. Simple as that. Only numbers came down from the very top. Those numbers became id-numbers and names by the mentioned above. Also it had nothing to do with shuffling planes around and opening new bases as these were done mostly last minute due covid19. Very little if none was known back in April when they fired 265 pilots. On the other hand quiet a few were called back for ongoing assessments. Hopefully they'll all get their jobs back before considering any external applicants.
