The C919 has been almost ready for a real long time now. Comac can't even get their license built DC-9 up and running. As of last year I think there were five flying a total average of around one flight segment daily. The C919 is an entirely new design intended to have more domestic Chinese content — fat chance it'll be in production real soon now, even less of a chance it becomes a serious contender. Meanwhile the Russians, who have significantly more experience with airliners, released the SSJ-100 to fairly positive reviews. Unfortunately the after sales support was trash and airlines struggled to keep it flying. Selling a competitive airplane is far more than just the plane itself. There's no way Airbus or Boeing see Comac as a threat. The real threat was Bombardier. Their C-series was an extremely competitive offering and Bombardier has the support infrastructure in place to sell it. Both Swiss and airBaltic seem to love it. Of course, Airbus bought a majority stake in the program.
