Makes sense on the limited code shares, but I would absolutely expect it to lower the effective fares. Yes, EAU-ORD as origin and destination would be the same, but with the code share, EAU-ORD-IAH-PHX would likely be maybe $100 more than ORD-IAH-PHX instead of the current $269-$349 it is booked as a separate, add-on ticket to CO's ticket.
Anyway, thanks for the answer, which is I should plan on booking on UA. May need to look at just flying out of MSP.
