Passenger Growth at Austin-Bergstrom International Airport
Passenger totals at Austin-Bergstrom International Airport have been on a steady rise, with 2024 coming close to record levels. The airport is expected to see even more activity in 2025. In 2024, approximately 21.7 million passengers traveled through the airport, which was about 333,000 fewer than in 2023 but still 675,000 more than in 2022.

- What’s the busiest day on record?
- Which airline carries the most passengers?
- Which airlines are seeing the most growth?

Days during SXSW, Spring Break, and the Austin City Limits music festival also feature in the top 10 busiest days.
