It seems to me since 3/3, that UA has been pricing CLE-ORD to match WN's full Business Select fare instead of the cheaper Anytime fare. IME, pre 3/3 UA was always in lock step with WN's lowest fare at the time. I just booked WN for a July 4 CLE-MDW trip because UA has been quoting $362 r/t on the barbie jet, whereas WN was $200 for a more comfortable seat on a 737. And no ridiculous $150 change fee if my plans change while in Chicago.
