Well, he is liked by some people in the industry. Gordon Bethune once said that Boyd is "as a good as they come." He also said that "if you want advice, the kind that is laid out whether good or bad, Boyd is the right person."
It is obvious why Boyd is against the DL/US merger; one of his biggest clients is DL. If he was to suggest that the merger was a decent idea, he would likely lose a large percentage of his 2 million in annual revenues.
Personally, I think he cares more about being on TV or in the paper than being accurate. He is always saying something outlandish and controversial. In my book, he has lost credibility after some of the off-color and ridiculous statements he made about DIA.
