The responsibility of selling/disposing of Baby was down to Lufthansa. IAG agreed to buy ONLY BMI Mainline. That was all IAG wanted
You make it sound like IAG have been hoodwinked!
AFAIK they agreed to buy the BMI group, encompassing Mainline, Baby and Regional, less whatever Lufty could dispose of seperately.
No point being naive about the sharp practice in big business, but let's be accurate here; IAG agreed to buy Baby!
