Searching Southwest, I found seats for a winter weekend getaway, departing Chicago MDW on Friday, January, 25, returning from Atlanta ATL on Sunday, January 27.
Other dates and longer trips are also available for travel through mid-February, excluding peak holiday travel.
Tickets can also be bought for $45 one-way and thanks to Southwest's lack of fees, you won't have to pay extra for bags or changes.
