The situation between DAL and MDW are different.

As for MDW, There are multiple gates available for and capacity to accommodate new carriers.

The issues is not what the airports were before, but what they are now and while one might think that two airports in a market means you can look holistically about competition across all airports in the market you're wrong. If that were the case everyone would not be fighting for slots at DCA or LGA and would be happy to increase service at the more distant airports like IAD, BWI and the like.
