In my opinion, Delta Air Lines hires based on a few measurable criteria subsequent to the Pilot Selection Committee's requirement to look good in their uniforms. This is in keeping with their vision of being the 6th (or 7th) Armed Forces of the USA SLASH the second branch of the U.S. Naval Air Forces. I mean, instead of Departments on their website, they're called Divisions. With that being opined, I also opine that a company can hire whomever they want. Merica baby.
