:chart_increasing: Why should this aircraft be added?
To complement the earlier suggestions of B717 (MD-95) and the MD-80 family by also including the in-between MD-90, the rarest (i.e. least of them were built) of the three. Similarly to the B717, it would be a good fit for the in-game american airports, having been operated by Delta on domestic routes.
