Both are busniesses who found Baby on their books
Seems that Baby wasn't wanted by anyone. Perhaps the business model was so flawed that neither LH, IAG or any future purchaser was interested.
Seems like the management involved in running Baby have more to accept as far as blame goes then two companies who never even wanted it.
Sadly the employees are the ones who live with the consequences of poor management but that still doesn't mean that IAG have to employ the pilots.
