Historically, and generally I would agree but DL at least was starting to show a slight preference for aviation university grads, or at least giving them bonus points in app scoring.

No indication that applies anywhere else, and I would not attend a brand-name aviation university just to get possible preference, or the R-ATP... there are much cheaper ways to do that. If money is no option, sure why, not do a package deal. Although if it were me I'd look somewhere other than Prescott... I drove through on a camping trip and it didn't like there were any coeds in sight.
