IT people can be an excellent source (point being, never write anything over a Company E-mail that you would not want your boss to read, because he probably will if it is interesting enough). However most airlines are much tighter over IT Admin than other businesses, which seems unlikely, but is true.

There is NO DOUBT Bombardier's sales across their entire current product range are scope constrained. Even Republic's Brian Bedford has been dithering as Frontier's use of the airplane is uncertain.

It is worth observing the C Series has not sold outside scope constrained markets either. Sailing's posts are probably correct and I think the lack of discounts and incentives are making the airplane uncompetitive in today's market.
