Houston – Memphis $93 Roundtrip for Late Summer/Fall Travel

Much lower than the usual rate on this route, fly between Houston and Memphis for $93 roundtrip on Southwest or United. Flights from Memphis to Houston are available for the same fare. This is part of the latest Southwest sale, which has been matched by United out of Houston's Intercontinental (IAH) airport. Travel is valid on Mondays, Tuesdays, Wednesdays, Thursdays, and Saturdays, from late August through mid-December. Thanksgiving travel is blacked out. Sale ends tomorrow night, so book quickly!

United flies out of Houston Intercontinental (IAH) and sells a basic economy fare, which only includes a small personal item. Southwest flies out of Houston Hobby (HOU) and is the better deal, as it includes two free checked bags and no change fees. Searching southwest.com, I was able to find seats departing Houston HOU on Saturday, August 25, returning from Memphis MEM on Monday, August 27.
