This. I don't think you can fly direct out of IND to anywhere without going through ORD. And if I had to guess, to fly from IND to ORD I bet you have to route through DET. Obviously this is sarcasm but it is very frustrating. It is easier to just drive to ORD and fly from there. By the time you get to IND x number of hours before your 45min flight and then land & change planes in ORD, it is just easier to start in ORD.
