Well, I have to assume that the yields for MDW were always way lower than for ORD based on the significantly discounted fares that CO was offering there to compete with WN/TZ. It would be nice to see ORD benefit from the upsizing of the 737 fleet, picking up some bigger planes at rush hour times to help manage the loads.

As for the lack of notification to people, CO is pretty bad about sending out an email saying that the itinerary has changed. But was the res tagged online as changed or just a fait accompli?
