With the MD88s leaving the fleet, and the 10 year leases on the 717s being up in 2023 what's the chance Delta also gets rid of the MD90 by 2023 and we reduce fleet types?

We can add the A319NEO & A320NEO to fill that gap.

Our narrowbody fleet would look like this:

C110
A319/20/21
737-700/800/900
B757-200/300

4 aircraft categories would be more efficient than 6 and the Airbus is a much more friendly plane for customers compared to the 717 or MDs.
