Austin City Limits (ACL) is the biggest October event affecting the OAK → AUS route, causing spikes in airfare, hotel rates, and airport transport demand. Expect higher passenger volumes at Austin-Bergstrom International Airport (AUS) during ACL weekends; plan ahead with pre-booked transfers, early arrivals, and confirmed return flights. On the Oakland side, October hosts smaller fall festivals and university events which can affect regional demand to OAK. CTA: If traveling for ACL, book flights and ground transfers early and consider arriving mid-week to beat the worst crowds.
