The point is that IAG have done NOTHING to even attempt to mitigate redundancies at BMI baby.
Neither were they ever going to.
The responsibility of selling/disposing of Baby was down to Lufthansa. IAG agreed to buy ONLY BMI Mainline. That was all IAG wanted. As Lufthansa couldn't sell Baby or Regional by the time the Mainline purchase deal HAD to be concluded the costs of disposal were deducted from the Mainline purchase price.
This cost reduction means that the costs incurred by IAG in providing redundancy packages will, effectively, be borne by LH.
Without a buyer Baby and Regional were already being made redundant at the time of purchase ........ by Lufthansa.
