Frontier has round-trip flights from Austin (AUS) to New Orleans (MSY) for $37, NONSTOP. $18 each-way. Flights November to January. Departures on Tuesday, Thursday, and Sunday. Extended Weekends available. Origin/Destination reversible.
Note: This was featured a few days ago for $29. It’s common to see it under $49, and anything higher than that isn’t a good deal.
Note: Frontier fares do not include a free carry-on bag. Only a small personal item, like a Jansport City Scout backpack is free. You can avoid paying for seat selection if you accept the randomly assigned seat prior to boarding.
Note: Frontier seats only have 28-inches of pitch; 2-to-3 inches less space than most other airlines.
