Lowest cost of Delta round trip Ohio to Orlando?

When in May is also a major consideration. Universal is opening a new park on 5/22 which is probably keeping some flights higher cost than would normally happen in May. Every airline's new labor agreements have kicked in and raised labor costs by in some cases as much as 30%. Personally I would be booking now with Delta and then watching for price drops, but I also fly enough to make use of those credits.
