Round trip
SDF to Houston is priced at $193 round trip on Southwest, about 35% below the typical $298 fare and a rare dip on this route. Houston makes for an easy long weekend around Space Center Houston and top-tier Tex-Mex, and it's a jumping-off point for Gulf Coast beaches, with Southwest's free checked bags adding even more value at this price.
