There is no reason to think this is a reason for bombardier to celebrate.... they gave away control of a $6 billion program for FREE! There is no way they will ever come close to recouping their investment on 30% of profits of a plane no body wants.
You can blame Boeing all you want but nobody was buying it... they only had two significant orders... air Canada did it to get the laws changed so they could pull heavy maintenance out of Montreal... delta only bought it because the Canadian government gave Bombardier $1 billion to absorb the loss of selling them for $19 million each!
And to top it off, if the c series program is so amazing why couldn't they get more than $0 for a controlling stake!
Don't forget Airbus won't push the cs300 too hard as it indirectly competes with their product line.... Both Boeing and airbus push the upgauging idea. It's why the 100-130 seat market is dead, just use a 320neo or Max8.
Maybe airbus will push the cs100 but it is at a disadvantage against the Embraer seeing as the 190e2 is just as efficient at a much lower cost.
And the biggest loser.... Canada... we have now subsidized an American company, one of the most profitable airlines in the world, as well as a multi-billion dollar European manufacturer..... that will employee workers in the US.
