Retiring a few of many types doesn't really get you much in structural cost savings. The big $ is in retiring sub-types, or full types: it simplifies frame scheduling, it eliminates parts inventory, it eliminates a pilot work group (think of inefficiencies from small groups across multiple bases). The 757, 753, 767 and 764 all have a common type rating.
Now, if you forecast that demand is going to be depressed for years and you've got a dozen 27-year-old A320s it's pragmatic to recognize they have little value to the carrier. Send them to retirement early.
