I further understand that the aircraft leases were paid up by Lufthansa - so BA are effectively getting 12 aircraft for free.
When you consider the timing of the Flybe announcement of starting domestic routes out of EMA (Baby had kept them out of EMA for years) - there doesn't seem to be as much benefit to BA if Baby had been sold.
If business is business why pay out large amounts of redundancy when recruiting Baby pilots into BA would improve the bottom line? BA may also get a better press by doing so.
