I had a hassle-free experience at the Spirit Airlines AUS Terminal in. Check-in was speedy, and the personnel were courteous, ensuring that everything proceeded smoothly. Security lines moved reasonably well, and there were sufficient seating spaces around the gates. Although the food choices were somewhat restricted, the terminal was clean and well kept. Boarding was well-coordinated, and the flight departed on schedule. All in all, when traveling with Spirit out of Austin, the terminal experience is a convenience and pleasant trip.
