I wasn’t claiming that B&B are the second coming of Herb Kelleher. The statement made was, “Every other merged major runs a mixed narrow body fleet”, as if that was a good reason for any other airline to operate a mixed fleet, and was also demonstrably false. The knock on Alaska is that they will never be successful because they are “afraid to evolve”, implying that operating multiple types is somehow a route to success. Southwest is the successful counterexample. Not saying the Alaska is another Southwest in the making, just that operating multiple types, inherited from a merger or not, is not per se a hallmark of a successful airline.
