For peak holiday travel, fly nonstop from Atlanta to New Orleans for $207 roundtrip on Delta.
Searching Delta, we found seats departing ATL on December 25, returning from MSY on New Year's Day, January 1.
This is a basic economy fare, but that does include a carry on bag plus a personal item. You don't get to choose a seat and you board in the last group, but who cares? If the goal is to get from A to B as cheaply as possible on Christmas, this is how you do it.
As always, you'll find lower fares available along this route for non-holiday travel.
