The cheapest I can find RT in ITA is $1549 for IND-NAN, which requires that 7 hour layover in LAX on the outbound . . .
The flights from LAX-NAN price at $1294 - one could try to find a separate flight to LAX from IND, but I tend to be really risk adverse to booking distinct itineraries (if the flight from IND is delayed, there's no recourse on separately ticketed trips).
