South Terminal at AUS

Allegiant and Frontier Joined the Main Barbara Jordan Terminal April 1, 2026

March 31, 2026, was the final day of operations at the South Terminal.

On April 1, 2026, the South Terminal officially closed, and Allegiant and Frontier flights will begin operating from the Barbara Jordan Terminal.

Same airlines. Same flights. Just one terminal.

Here’s what this means for you, and for the future of AUS:

Why Is the AUS South Terminal Closed?

Once the South Terminal officially ceased operations on March 31, 2026, the structure will be permanently removed to make way for the New Midfield Taxiways project, a key infrastructure addition that supports the continued growth of AUS.

The midfield taxiways are an enabling project within the Journey With AUS expansion program. Completing them allows the airport to move forward with future projects, including the planned new Concourse B and connecting tunnel, which will expand gate capacity and improve connectivity across the airfield.

Simply put, this step helps us prepare for the future of travel in Central Texas.

What Can Passengers Expect?

Starting April 1, 2026:

• All Allegiant and Frontier flights depart from and arrive at the Barbara Jordan Terminal
• All commercial airlines at AUS operate under one roof
• Travelers experience a more unified and streamlined airport experience

If you’re flying Allegiant or Frontier after April 1, head directly to the Barbara Jordan Terminal for check-in, security screening, and departure.

Key Date to Remember

• April 1, 2026 – Allegiant and Frontier begin operating from the Barbara Jordan Terminal

If your travel falls after this date, please note that Allegiant and Frontier flights will arrive and depart from the Barbara Jordan Terminal.

Parking and Shuttle Information

We know parking is top of mind for many travelers, and we’ve planned carefully to support a smooth transition.

If you depart from the South Terminal on or before March 31 and park in a South Terminal parking lot, but return after April 1, you will arrive at the Barbara Jordan Terminal.

To assist returning passengers, the ABIA Parking shuttle between the two terminals will continue operating until the South Terminal parking lot has been fully vacated. This ensures you can easily access your vehicle and complete your journey home without added stress.

A Moment of Appreciation

Since opening on April 13, 2017, the South Terminal has served millions of travelers and played an important role in AUS’s growth. As we prepare to close this chapter, we do so with gratitude and with excitement for what’s ahead.

Removing the South Terminal enables us to complete the New Midfield Taxiways and advance major expansion projects like the future Concourse B and Tunnel. These improvements will help AUS better serve our community for years to come.

We welcome Allegiant and Frontier passengers to the Barbara Jordan Terminal beginning April 1, bringing all AUS airlines together under one roof.
