I think anyone with half a brain could have changed their minds after seeing what I'm guessing was wild evidence in favor of keeping E+.

It's irrelevant that he didn't have access to UA's books. You're missing the bigger point - he came into the merger predisposed to killing off E+. Was so brainwashed by the PMCO mindset that he couldn't fathom how having fewer seats on a plane could translate to profitability, loyalty, yield management, etc. Seems a bit myopic to me.

Not the type of leader I'd want running my company.
