Just announced... Airbus is buying 50.01% into the C Series.
They will open a second production line for the C Series in Alabama where Airbus is already located and will build aircrafts for US market. They will also need to hire people to build these aircrafts.
So jack ass Trump can't go against that now because of the jobs it will create in the USA.
As for Boeing well I'm sure they are the biggest losers here. They have no aircraft to compete in that category and would have to spend billions upon billions to design, test and build one and it would be years before they get it to the market.
