Any one know La OT

I will be flying to MSY New Orleans airport frequently this coming year. Do any of you LA guys or anyone know inexpensive transportation to Baton Rouge. This last time I rented a car at MSY and dropped it off at BTR. $150.OO one way+ fuel.The taxi ride back was the same. This comes out of my pocket. Looking for inexpensive alternative.
