Delta Airlines made a strong move, displacing American Airlines as the airport’s second-largest carrier with an ambitious growth plan and the introduction of a slew of new nonstop routes that catapulted the carrier to the forefront, powering its ascension and cementing its status as a significant force in Texas. This drastic change occurs as Delta solidifies its foothold in one of the regions with the most rapid growth by outperforming American Airlines in an intense battle for passengers and routes.

Austin Bergstrom International Airport (AUS) has witnessed a shift in its airline rankings, as Delta Air Lines has now overtaken American Airlines to become the airport’s second-largest carrier. The Atlanta-based airline, a key member of the SkyTeam alliance, now sits behind only Southwest Airlines, which remains the dominant player at the Texas airport. This change was confirmed in April, with Delta carrying over 302,000 passengers compared to American’s 298,500, marking the first time Delta has surpassed American in terms of passenger numbers.

The Rise of Delta

American Airlines had held the second spot at Austin for several years, maintaining its position from 2021 to 2023. From March to December 2022, American Airlines carried twice as many passengers as Delta. Even during the COVID-19 pandemic, when air travel came to a near halt globally, American Airlines maintained its strong position. However, Delta has aggressively expanded its footprint at Austin since 2023, launching several new nonstop routes. These additions include new flights to Cancun, San Jose del Cabo, and Palm Springs, all of which are seasonal services starting later this year. As Delta has expanded its presence, American Airlines has scaled back, eliminating 35 nonstop routes from Austin, including key tourist spots such as the Bahamas, Costa Rica, and the Dominican Republic.

Delta, in contrast, has capitalized on the routes American Airlines dropped, picking up several of the same domestic markets. These include Indianapolis, Jacksonville, Las Vegas, Memphis, Nashville, New Orleans, Orlando, and Tampa, among others. The competition between Delta and American Airlines for second place at AUS has been fierce, with both airlines vying for a larger share of the airport’s increasing passenger traffic.

American’s Route Reductions

In addition to halting flights to several leisure destinations, American Airlines has reduced its overall presence in Austin. Since the start of 2023, the airline has discontinued several routes, including flights to popular holiday destinations such as the Dominican Republic and Jamaica. This has allowed Delta to fill the void by adding new routes to key domestic markets. As a result, Delta now offers a broader range of destinations, with year-round flights to cities like Atlanta, Boston, Cincinnati, and Detroit, as well as seasonal flights to destinations such as Cancun and Palm Springs.

Delta’s Growing Network at AUS

Delta’s rapid expansion at Austin has been fueled by its strategy of adding new nonstop services. The airline now operates a wide variety of year-round and seasonal routes, including connections to major hubs like New York JFK, Los Angeles, and Minneapolis/St. Paul. These new routes are designed to cater to both business and leisure travelers, offering convenient options for passengers flying to and from Austin. With the addition of these new routes, Delta has positioned itself as a key player at AUS, competing head-to-head with American Airlines for the second-largest carrier spot.

The Competitive Landscape

The competition between Delta and American Airlines for the second-largest position at Austin is intense, but Southwest Airlines remains the dominant airline at the airport by a significant margin. From January to April 2025, Southwest carried 2.6 million passengers, accounting for 41.6% of all passengers at AUS. While Delta and American continue to battle it out for second place, Southwest continues to dominate, maintaining its lead by a wide margin.

For the first four months of 2025, American Airlines carried over 1.1 million passengers, representing about 17.4% of the total passengers at the airport, while Delta brought in just one million passengers, accounting for 16.1%. While the two carriers are close in numbers, Southwest’s continued dominance highlights the ongoing competition for a larger share of the airport’s passenger traffic.

The Top Routes at Austin

The most popular routes from Austin remain heavily dominated by Southwest Airlines, with the top three routes—Atlanta, Denver, and Dallas/Fort Worth—each carrying over half a million passengers annually. The route to Atlanta, served by Delta, Frontier, and Southwest, remains the busiest, followed by flights to Denver, served by Frontier, Southwest, and United. The Dallas/Fort Worth route, operated exclusively by American Airlines, continues to be a major contributor to the airport’s overall traffic.

The Future of Austin’s Air Travel Market

The battle for second place at Austin is far from over, as Delta and American Airlines continue to adjust their networks in response to market demand. While Delta has made significant strides by adding new routes, American Airlines remains a key player at the airport, albeit with a reduced presence. The competition between the two carriers will likely continue, especially as passenger numbers grow and more airlines seek to capitalize on Austin’s expanding travel market.

Looking ahead, it’s clear that the airline landscape at Austin Bergstrom International Airport will remain competitive. Delta’s expansion shows its commitment to strengthening its position at the airport, while American Airlines will need to reassess its strategy in response to the growing competition from its rival. As the demand for air travel continues to increase, both carriers will be looking to capture a larger share of the market, with Southwest Airlines continuing to dominate the airport’s overall traffic.

Conclusion

Delta Airlines surpassed American Airlines to become the second-largest carrier at Austin Bergstrom as a result of accelerated route additions and high market growth. This major change establishes Delta as a strong force in the expanding air travel market in Texas.

Delta’s rise to the position of the second-largest airline at Austin Bergstrom International Airport represents a major shift in the city’s aviation sector. With American Airlines pulling back on several routes, Delta has seized the opportunity to expand its presence, offering more nonstop options to key destinations across the United States. However, the competition for second place remains fierce, with both airlines locked in a battle for a larger share of the growing Austin market. As Southwest Airlines continues to dominate, Delta and American will need to adapt and innovate to capture the attention of both business and leisure travelers at one of the fastest-growing airports in the United States.
