I'm still confused. This Ska-beerswiller chapie appears to be talking out of his wotsits.
I'm pretty certain that Astraeus Pilots were not involved in flying Aer Lingus Aircraft on Aer Lingus routes. Some were involved in Line Checking to Astraeus procedures. Astraeus A320 pilots were recruited for their own A320 operation.
I'm also (fairly ) certain that Astraeus are union affiliated.
It therefore follows, that the "loss" of the Aerlingus "contract" should have no material effect on Astraeus Pilots.
At least now, if Aer Lingus pilots sadly end up losing their jobs, they will have no-one left to blame, but themselves.
