Southwest Is Offering $47 Flights In A 3-Day Flash Sale

'Tis the season. 😊

Summer is kicking off with yet another round of cheap airfare opportunities.

Southwest Airlines is offering one-way flights as low as $47 in a 3-day flash sale that ends Thursday night.

These deals aren't the most eye-popping we've ever seen. But they do make for well-priced weekenders, or a convenient way to skip legs of cross-country road trips when you're tired of the car.

Some of our favorite options include a $47 one-way flight from Charlotte to Baltimore, a $49 flight from New Orleans to Nashville and $79 flights from New York City to Austin or Chicago.

If international travel is more your style, there's a $149 flight from Los Angeles to Costa Rica, too.

Most of the deals are valid for flights from Aug. 23 through Dec. 14, and they're limited to certain days of the week.

But not to worry: Since airfare is generally cheaper all summer long, you may be able to book one leg of your trip at flash sale prices and another on a non-restricted day for the regular price without too much shock to the wallet.

Happy travels!
