Exactly, IAG said they would only buy the airline bmi and, somewhat reluctantly, bmibaby, which they closed down after six months or so. IAG insisted they didn't want the pension scheme as part of the deal. That left LH with a pension scheme to get rid of and the outcome is well documented on this forum.
My concern is for the Aer Lingus pensioners. What safeguards do they have if the plug is pulled on their pension scheme?
RTFQ?
