Southwest Airlines will transition its entire technology infrastructure to Amazon Web Services (AWS) by 2028, aiming to replace legacy on-premises systems with AI-driven, cloud-based architecture. According to a June 17, 2026, announcement from the airline, the partnership seeks to increase operational reliability and speed for its 134 million annual passengers by integrating agentic AI tools into core business functions.
Why is Southwest shifting to a cloud-based model?
Southwest Airlines is moving to the cloud to modernize its internal systems and improve the speed of its customer-facing digital platforms. Lauren Woods, the airline’s Chief Information Officer, stated that the strategy focuses on enhancing performance and reliability across its operations and software development teams. By migrating to AWS, the airline intends to simplify its technology environment, allowing its 70,000 employees to make faster, data-driven decisions. This transition marks a significant departure from the company’s historical reliance on on-premises data centers.
How are AI agents changing software development?
Southwest is currently utilizing Kiro, an AWS-native agentic coding service, to refactor legacy code on its primary website, Southwest.com. According to Swami Sivasubramanian, Vice President of Agentic AI at AWS, more than 2,700 developers at the airline are using these tools to automate testing and generate infrastructure. This shift is designed to reduce the time required for complex tasks from hours to minutes. The airline is also adopting an “AI-Driven Development Lifecycle” (AIDLC), where AI agents assist in workflow management while engineering teams retain final oversight and validation responsibilities.
Southwest Airlines currently carries more passengers on nonstop flights within the United States than any other carrier, according to data from the U.S. Department of Transportation.
What are the implications for airline operations?
The integration of agentic AI is expected to impact three specific areas: customer experience, daily airline operations, and software maintenance. By deploying AI agents to handle routine tasks, Southwest aims to scale its operations more efficiently as it serves 120 airports across 12 countries. Unlike traditional automation, which follows rigid rules, agentic AI is designed to adapt to changing operational variables. This capability is intended to help the airline maintain its “hospitality-first” business model while managing the logistical complexities of high-volume air travel.
Comparison: Legacy Systems vs. Cloud-Enabled Architecture
| Feature | Legacy On-Premises | AWS Cloud-Enabled |
|---|---|---|
| Scalability | Limited by physical hardware | Dynamic and elastic |
| Development Speed | Long, manual cycles | Automated via AI agents |
For organizations looking to modernize, Southwest’s approach demonstrates that AI adoption is most effective when it augments human oversight rather than replacing it. Keep your engineering teams in the loop to validate outcomes.
