Calling the shots is what you can do if a product is below spec or delivered late. PW and Airbus could be avoided this, or at least they could have had a stronger hand, if they hadn't been late and made simple errors. Rotor bow in this day and age? All these years of making cabins and can't make them to schedule?
I think that they're probably ordering the wrong aircraft though. A320neo will be the better aircraft, and the A350 is probably more popular with passengers.
