Thanks for the answer! I am based on the West Coast and a good part of my flying is in fact international and coast-to-coast. Most CO flights require me to go thru TX, which is not nice, while US goes thru PHX.
Likely, the route map argument will win, unless United (which I also fly fairly often) gives CO Elites access to E+.
