For travel over the 4th of July holiday, fly nonstop from Chicago to Nashville for $326 roundtrip, nonstop, on American Airlines.
Searching AA.com, I found seats departing ORD on Wednesday, July 3, and returning from BNA on Saturday, July 7.
This fare includes a carry-on bag and a small personal item.
Seat selection is available in advance with the purchase of this fare.
