Unlike Alaska's current fall airfare sale, which is more limited to the West Coast, Southwest's network of flights covers much of the United States, offering many non-stop options from East Coast cities like New York City, Orlando, or Atlanta.

How to find cheap flights on Southwest

To find the best prices, use Southwest's Low Fare Calendar. From there, you can pick your months of departure and return and see the cheapest prices for every day in the month.

The cheapest tickets will be the "Wanna Get Away" fare, which includes two checked bags for free, no change fees, a flight credit if you need to cancel, plus frequent flier mileage earning potential. Those are huge savings considering you can fly on a $49 fare route for cheaper than checking two bags on almost any other airline.

For about $30 more, the "Anytime" fare is fully refundable with same-day standby options, while "Business Select '' for $50 to $100 more comes with priority boarding and security as well as a premium drink. As with all Southwest flights, you may not pick your seat ahead of time.
