Insights shared by verified travellers who flew the route from San Diego to Austin 
CarlosFlew with Alaska AirlinesSAN-AUSJun 2025
Get to the San Diego airport early. The security line will be long. Also, if you're flying Alaska Airlines and don't check in online, go to the Alaska Airlines "Agent Assit" counter first. Don't be like me and go to the Alaska Airlines "Bag Drop" line. That was a bit confusing. If you're flying Alaska Airlines.
