The efficiency of the Spirit Airlines AUS Terminal was unexpectedly high! Although I anticipated large lines, check-in went really smoothly. Throughout the procedure, the personnel helped me and was friendly. There were plenty of seats and charging outlets in the tidy terminal. You can get a quick snack, but there aren't many dining options. All in all, a seamless flight for a low-cost carrier. Simply be sure you get there early to save yourself from last-minute anxiety.
