The holidays are a season of giving. While you count pennies and hunt for deals on gifts for your family and friends, maybe you should be giving something back to yourself. Something like a little vacation in the spring.
The logic isn't great, but if it somehow resonates anyway, Southwest is running a three-day sale with one-way flights as cheap as $40. The cheapest tickets are for shorter flights -- for instance, Los Angeles to Las Vegas for $79.96 -- but there are deals all over the US and even a few that can get you out of the country.
