Doug Parker couldn’t organise a proverbial in a brewery. He was good at running a low cost operation at America West. Then did a good job of keeping a dysfunctional US Airways alive by cutting costs and turning it into a pseudo low cost airline and then destroyed American by applying the same MO. If you’ve travelled on AA recently, it’s a non stop sales pitch from T/O to touchdown.
Oh and multiple DUI’s. Not that that is indicative of his management abilities but certainly a measure of his character.
