- why order the -7 when for marginally higher fuel burn and 1 extra FA you can fly a -10 that has significantly higher revenue potential. It really does not cost much more to fly a max 10 with 130 pax than a -7 with the same number, so why limit your potential revenue. Remember the -7 caries a lot of the structural weight of the -10.

- we already fly the 220. There is a popular notion at DL that the 220 “doesn’t work” on short routes but that’s just not true. The 220 was our first jet, and for almost 5 years our only jet, with this new generation of modern engines. While it’s obviously better on longer flights so is the NEO and the MAX. Using the 220 on short hops may not be the best use when we only have a few new planes and have a bunch of -88s and 717s, but with those gone it will do just fine on short legs. It’s not like there is something magical about the 220 that doesn’t apply to other planes with the similar engines.
