Travel Tips
When flying from RDU to AUS, consider booking your flight at least three to four weeks in advance to secure the best rates, as this business-heavy route can see price spikes closer to departure dates. If you are flying on a non-stop flight, airlines like American and Delta often offer the most consistent schedules. Pack a light jacket regardless of the season, as airplane cabins and Austin’s air-conditioned venues can be chilly compared to the humid outdoors. Upon arrival in Austin, utilize ride-share apps or the CapMetro bus service for an affordable transit into the downtown area, which is only about 7 miles away from the terminal. Finally, do not forget to check the local festival calendar; massive events like South by Southwest (SXSW) or the Austin City Limits (ACL) music festival can significantly impact both flight availability and hotel pricing throughout the entire Austin area.
