RE: CSeries Anytime a new plane is manufactured there is going to be a few problems,even changing suppliers for the better in the long run
But I'm sure there is close communication between airliners and Bombardier about the CS,why else would AirAsia make a comment about a possible order of 100+ cs300.
Boeing and AIRBUS can only bad mouth Bombardier about the CS for so long,it's a whole different animal
not just slapping a new engine on existing aircrafts
