so on these two orders alone COMAC has to deliver 200 C919s in the next seven years...that's quite a task considering they are still only producing in the single digits.
That's not very demanding, considering COMAC have a publicly stated target of 150 per year by 2028.
And they likely could sell even more C919, given the 10+ year waiting list at Boeing and Airbus.
Given this long-term airliner shortage, it doesn't look like ticket prices will drop anytime soon...
