DL's cuts indicate that the premiums paid by these business travelers (my company's travel policy certainly is restrictive, readily trading my time for their money) weren't sufficient to support profitable non-stop service. This leaves a lot of surplus infrastructure, but the airport authority can't exactly relocate a concourse to ORD.

The CVG market will get the level of service it can support. DL flyers will have to assess the value of their time and DL RJ's vs. connections on DL or other carriers. Businesses and people that really value flight frequency and high numbers of non-stop destinations may choose to locate elsewhere.
