Middleware for Legacy Airport Systems Market Report 2026

The middleware for legacy airport systems market size has grown strongly in recent years. It will grow from $1.54 billion in 2025 to $1.68 billion in 2026 at a compound annual growth rate (CAGR) of 9.3%. The growth in the historic period can be attributed to expansion of legacy airport infrastructure, increasing passenger traffic volumes, early adoption of airport IT modernization initiatives, growth of integrated airport management systems, rising demand for operational efficiency.

The middleware for legacy airport systems market size is expected to see strong growth in the next few years. It will grow to $2.37 billion in 2030 at a compound annual growth rate (CAGR) of 9%. The growth in the forecast period can be attributed to increasing investments in smart airport transformation, growing adoption of cloud-based airport platforms, expansion of data-driven passenger processing systems, rising cybersecurity requirements, increased focus on system interoperability. Major trends in the forecast period include increasing adoption of middleware-based system integration, rising demand for real-time airport data interoperability, growing use of api-driven airport applications, expansion of hybrid deployment architectures, enhanced focus on legacy system modernization.

The increasing adoption of cloud-based solutions is expected to drive the growth of the middleware for legacy airport systems market going forward. Cloud-based solutions are services or applications hosted and accessed over the internet instead of being installed on local computers or servers. The rise in adoption of cloud-based solutions is due to cost efficiency, reducing the need for expensive on-premises infrastructure and lowering maintenance expenses. Middleware for legacy airport systems facilitates the adoption of cloud-based solutions by seamlessly integrating outdated infrastructure with modern cloud platforms, enabling efficient data exchange and smoother system modernization. For example, in May 2025, according to Cloud Zero, a US based cloud cost-intelligence and FinOps platform, global cloud computing grew to $912.77 billion in 2025, up from previous years, highlighting rising adoption despite over 20 percent of organizations lacking clear visibility into their cloud costs. Therefore, the increasing adoption of cloud-based solutions is driving growth in the middleware for legacy airport systems market.

Major companies operating in the middleware for legacy airport systems market are focusing on advanced technologies, such as the middleware-driven data orchestration layer, to enable seamless integration of disparate legacy subsystems, streamline real-time data exchange, and enhance operational efficiency through unified and intelligent airport management. Middleware-driven data orchestration layer is a centralized framework that manages, integrates, and synchronizes data flow between diverse legacy and modern airport systems in real time. For instance, in October 2025, WAISL Limited, an India based company specializing in digital transformation and IT services for airports, launched its Digital Twin-Powered Integrated Airport Predictive Operations Centre APOC at Rajiv Gandhi International Airport, Hyderabad. The launch was inaugurated by Union Minister of Civil Aviation Ram Mohan Naidu Kinjarapu, who commended the innovative efforts of the airport’s leadership and technology partners. This initiative marks India’s first fully integrated digital twin-powered APOC, covering terminal, airside, and landside operations. The system integrates over 40 modules and monitors more than 100 key performance indicators KPIs. It is designed to handle over 40 million passengers annually and enhances airport efficiency through predictive and intelligent operations.

In May 2025, Société Internationale de Telecommunications Aerocaptures SITA, a Switzerland based company providing IT and telecommunications services to the air transport industry, partnered with Innova Solutions, Inc. to modernize transit platforms and explore AI-driven innovation. Through this partnership, SITA and Innova Solutions aim to expand SITA’s legacy transit and airport middleware systems by migrating them to a scalable, cloud-based infrastructure that improves integration, resilience, and AI-driven innovation. Innova Solutions, Inc. is a US based company that provides middleware for legacy airport systems.
