[07/17/2018 @ 11:33 PM] Old-post clean-up. Fare gone. Removing from deal list.
Frontier has round-trip flights from San Antonio (SAT) to New Orleans (MSY) for $39, NONSTOP $20 each-way. Flights on Thursdays from August to November. Other days of the week are $49 each-way. Origin/Destination reversible.
Note: Frontier fares do not include a free carry-on bag. Only a personal item (like a small-backpack) is free. Checked bags cost +$35 each-way. You can avoid paying for seat selection if you accept the randomly assigned seat prior to boarding.
