Here's how travel costs go up for Cincy. The average flight distance increase in the Big 12 for Cincy is about 150 miles per school so that is some cost increase. The bigger issue for Cincy is that Olympic sports generally fly commercial and the Big 12 schools are not located in ideal locations for commercial flights relative to the AAC. In the Big 12, you have towns like Lubbock, TX, Waco, TX, Manhattan, KS, Ames, Iowa, Stillwater, Oklahoma.

"We've had a lot of discussions about that obviously over the last several months, and we know travel-wise there'll be some additional expenses.
