All true, but the largest single a/c type in the fleet is MD-80s which require only 3 f/as minimum. The company made much of the fact that the 737s that are replacing the MD-80s would be configured such that they would require 4 f/as. At some point the most of any a/c type in the fleet will be 737s. And, in the post by IORFA above, the company (without using the actual words, "we goofed"), admitted that the 2300 reduction they want in the f/a corps does not include the lesser demand for f/as due to the 737 reconfiguration.
I do not believe that this MC Extra plan just suddenly arose after the bankruptcy term sheet was presented to the union. They knew about it, and either no one thought of the reduction in f/a demand created by this plan or they decided that admitting how many f/as they really wanted to get rid of would create too much of a public relations firestorm.
At Centreport looking good is infinitely more important than doing good.
