"Question for the pilots: what are your opinions on the viability of the Comac C919 and Irkut MC-21? Both of those have even wider fuselages than the A32X. I'm fully aware that they're a while away from launch, never mind that there's no public news about longer versions yet - but to me at least it looks like there could possibly be some competition for the existing duopoly at some point in the distant future?"
Easy - nil.
