Thats 1,579 aircraft delivered per year for the next 19 years or 132 aircraft per month or 4.5 per day continuosly)!
Which is quite realistic with a A320 and B737 output of more than 1 every day.
The questions remains what happens with old aircraft, they are going to be replaced by the new ones. I sincerely doubt that all new arriving aircraft are being additional ones. Soon all those 767, MD80s, 757 have to go to the scrapyard.
