Southwest Airlines will shift most of its IT infrastructure to Amazon Web Services by 2028, making AWS its primary cloud provider. The airline is moving away from largely on-premises systems to support customer service, flight operations and software development.
The migration is already under way on Southwest.com, where the airline is using AWS’s Kiro coding service to modernize the site. Southwest says more than 2,700 developers are using Kiro to build features, automate testing and provision cloud infrastructure. The carrier is also pushing an AI-driven development lifecycle built on AWS tools, with AI agents assisting engineers while teams retain control over outputs.
The move gives Southwest a clearer path to faster release cycles and tighter operational control.
