Although the temperature may have only just started to cool down, it’s not too early to make your warm-weather contingency plans.

Southwest Airlines is having a sale on winter flights, with one-way airfare as low as $49. The deals are valid from November 28 through December 19, and January 3 through February 13, 2019. Deals for international flights to Caribbean destinations are available through March 6, 2019.

Fair warning: You won’t be able to use these deals to plan your winter weekend getaways. The lowest airfare is not available on Friday and Sunday flights and international deals will only show up for flights on Tuesdays and Wednesdays.

However, if you’re looking for an excuse to take time off from work, the low prices could make time off requests a lot more enticing.

From Phoenix, there are $49 flights to San Diego and the same price is available between Atlanta and Nashville. For $79, travelers in D.C. can ease down to New Orleans or people in Oakland can escape to Denver. Those battling the snow and wind in Chicago can find warmth in Dallas for only $99. Winter warriors stranded in St. Louis can make a break with a one-way flight to San Jose for $129.

The deals are available until October 4 at 11:59 p.m. (in the flight’s originating city).
