You can't spell South by Southwest without the airline namesake coming to mind, which is why you should fly them down to the festival this year with this excellent fare deal.
Nonstop flights from Chicago-MDW to Austin for $189 roundtrip are available on select departure dates that stretch over the festival that runs from March 8 through March 16, 2019.
Flights at this price are available on Tuesday, Wednesday, and Saturdays; however, you might find a similar price with a connection on other days of the week. For those of you wanting to skip the frenzy of the festival, travel is valid through May 22, 2019.
As an example, searching on the Southwest site, I found seats departing MDW on Saturday, March 9 and returning from AUS on Tuesday, March 19, 2019, stretching almost the entirety of the SXSW dates.
If you aren't based in Chicago, no worries, we have a whole list of fare deals to the festival from airports all across the U.S. to Austin (AUS) posted here.
