I'll stick with UA on many of my flights. E+ wasn't what took me to them (it's nice though), PHL did. I will do anything to not have to go near PHL, and that translates to flying UA. CLT is good but out of the way to go south then west (and usually the longer of the flights where I go end up on RJ's). Flying UA 2 segments tomorrow. I'm waiting to see if they take me out of the E+ seat I booked weeks ago.
