Allegiant Air AUS Terminal occupies the South Terminal of Austin-Bergstrom International Airport (AUS), a less formal and customer-focused terminal besides the airport's main terminal. This terminal is rented by only a few low-cost carriers, including Allegiant, and is intended to be simple and efficient. Allegiant provides minimal services such as ticket purchase, check-in, and bag drop through manned stations and self-service kiosks. Passengers are encouraged to check in online or via the Allegiant mobile app before their arrival. Baggage service, including help with delayed or damaged bags, is handled through Allegiant's terminal support staff or via its customer service phone number. In-terminal signage displays real-time flight information and is also available digitally. Allegiant customer service is offered online, by phone, and at the ticket counter.

Allegiant Air flies out of the South Terminal at Austin-Bergstrom International Airport (AUS), where they provide a special and hassle-free travel experience apart from the primary Barbara Jordan Terminal. The South Terminal is at 10000 Logistics Lane, Austin, TX 78719, and can be reached using U.S. 183 South to Burleson Road. For arriving passengers at the Barbara Jordan Terminal, there is a free shuttle service every 20 minutes that takes the traveler between the two terminals in 15 to 20 minutes, depending on traffic flow.

Within the South Terminal, travelers will discover a casual ambiance with necessary conveniences. The terminal has "grab and go" food and beverage services, an outdoor patio space to bask in Texas sunshine, and complimentary Wi-Fi throughout the complex. The decor is offbeat, and the terminal offers a cozy setting for travelers.

Allegiant Air Terminal AUS offers ticketing services at the South Terminal, with hours of ticket sales generally available for one hour after every scheduled departure. It is worth mentioning that Allegiant does not accept money orders, checks, or cash at any airport facility; transactions have to be done using credit or debit cards.

For check-in, travelers have several choices:

Online Check-In (Free): Begins 24 hours prior to departure to enable travelers to check seat selections and bag reservations prior to printing boarding passes.

Mobile Check-In through the Allegiant App (Free): Travelers can check in via their smartphone for easy, paperless boarding passes.

At Airport Boarding Pass Print Out ($5 per Boarding Pass): Customers who need an agent to print their boarding pass at the airport will pay $5 per boarding pass. Nevertheless, this fee does not apply to customers who must check in at the airport ticket counter.

Passengers should report to the airport at least 2 hours before their planned flight departure. All passengers aged 18 years and above are required to show an acceptable mode of identification, including a driver's license or passport.

As far as baggage rules, all Allegiant travelers can bring one personal item aboard for free. Other carry-on bags and checked bags incur fees, which are less expensive if booked ahead of time in Allegiant's "Manage Travel" area. Airport prices are more expensive, so prepaying for baggage is advisable to save money.
