Delta has already taken 84 of its 130 737-900ERs on order with its newest one being delivered SEP 1. They have 25 of the 45 A321s already on property with the last one deliver AUG 11th.

So basic math says 141 deliveries. Still short of a 1-1 MD80/90 retirement and, as I said basically flat growth. The only way DL grows, as of what we know today, is if they keep the MD-90 into the 2020's.

So how am I totally wrong? If you have facts put them out there. I basically just googled DL aircraft orders and used Airfleets as a source.
