The checkin was fine but pick up was way slow. The driver had just left for the other terminal that recently opened and I had to sit and wait for 30mins. Waiting with my luggage outside for 30 mins in Texas heat is too long. 15mins is fine. 20 is a little long but i would return as a customer. I will try other options at AUS for parking. For shuttle speed, Please be clear if you are asking about how fast they went (mph)or how quickly it picked us up. Obviously I assumed picking us up. Their speed was fine.
