One key to a good trip through AUS is to minimize your time within the sterile area as the activities are very limited. The restaurants within security are relatively expensive and serve very poor food especially those that purport to be airport versions of the local fare. No Starbucks. If you can avoid evening departures as this is when the live musicians play in the center area causing an already noisy airport ambience to become even worse. If you can avoid early morning flights as the TSA security theater is made worse by inadequate entrances resulting in lines that stretch the length of the terminal. For those with checked in luggage the lengthy wait times upon arrival can be problematic; however the airport restrooms are some of the best in the US. AUS has both a good heel bar and an excellent massage kiosk. The roads to the airport are very very poor and the signs are confusing at best just like the rest of the city so plan lots of extra time to get to the airport on the terrible Austin roads. The car rental facility is on site although "customer service" can be a problem.
