Good luck to Bombardier. Hopefully, Delta will negotiate the price of a sizeable fleet of CS300s. This aeroplane would be a great fit for them. In light of the Flydubai prang in Russia, it looks like the NG could be in for a downturn in sales if the Russian investigators preliminary findings prove accurate. Time for Boeing to move on to a 'clean sheet' replacement and catch up to the technology found in the rest of the industry.
