Delta is to speed retirement of its oldest fleet members, mostly the venerable MD-88 and 90’s. Some are as much as 28 years old.
Delta is said to be delighted with its new A220’s and these will help speed up the withdrawal.
While ideal for many routes the MD’s are not as efficient and becoming costly to maintain.
The last of 79 MD-88 will leave service in 2020 with the 37 MD-90’s by 2022.
