A total of about 21.67 million passengers departed and arrived at the Austin-Bergstrom International Airport in 2025, marking the year as the third busiest for the airport.
The details
Passenger traffic marked 2024 as the airport’s second busiest year, following 2023 and 2022’s record-breaking totals.
The busiest airline for the airport was Southwest Airlines, with 8.9 million passengers, similar to 2024. Southwest Airlines officials recently announced plans to expand at ABIA, backed by a $5.5 million economic incentive deal between the airline and the city of Austin.
What else?
The airport is currently undergoing a multiyear expansion program designed to upgrade facilities and increase capacity to address the record-breaking passenger traffic in recent years.
The expansion program includes several projects, such as a new baggage handling system, facilities and passenger gates, various airfield upgrades, and the construction of new taxiways and a second terminal.
In 2025, officials broke ground on a new parking garage with 7,000 spaces opening in two phases, as well as broke ground on the Atrium Infill project.
