Pack your bags and leave the winter coat at home.

Just in time for the winter freeze to arrive, Southwest Airlines is running a huge flash sale this week with super inexpensive flights as low as $49 for this winter and into spring.

This special sale won’t last long, only until Thursday, Dec. 13, at 11:59 p.m. But with travel dates available from Dec. 18 to May 22, 2019, you can start thinking about that post-holiday getaway to get over your winter blues. Some blackout dates around Christmas and New Years do apply.

Some of the best fares we found include:

Atlanta to Fort Lauderdale for $84 and Orlando for $85.

Los Angeles to both Las Vegas and San Francisco for only $61.

Denver to San Francisco and San Jose for $89.

Sacramento to San Diego for $49.

Orlando to New Orleans for $91.

Milwaukee to Nashville for $62.

Minneapolis/St. Paul to Denver for $97.

Fort Lauderdale to the Cayman Islands for $71.

Boston to Baltimore for $70.

New York, La Guardia and Newark to Chicago, Midway for $91.

Providence to Washington, D.C. for $62.

Salt Lake City to Las Vegas for $61.

Washington Dulles to Fort Lauderdale for $92.

All airfares listed are for one-way, nonstop service only. However, it’s likely to get a comparable price on your flight back home. Fridays and Sundays are generally not available, so it’s also important to be flexible with your dates (and make sure you have some vacation days lined up).

You can check airfares from your departure city of choice and book flights on the Southwest Airlines sale page.
