You should add the feature of search for multiple cities at once. For example depending on the price I have flown out of the Cincinnati, Dayton, Columbus, and Indianapolis airports. Believe it or not, it takes me about the same amount of time to get to each.

EDIT: It appears you include nearby airports as well in your search, but I would still like to be able to chose which are included. Dayton is included in Cincinnati searches and Indianapolis is included in Columbus searches, but I can't search for all four.
