The report identifies international travel as the largest segment of the market, supported by the UK's role as a major aviation hub. International passenger traffic reached nearly 260m in 2024.

While passenger services account for most airline activity, air freight is forecast to be the fastest-growing segment through 2034. The report projects cargo operations will expand at a CAGR of 6.3%, driven by e-commerce growth and demand for time-sensitive shipments.

The projected growth is likely to increase pressure for investment in airport infrastructure, cargo handling facilities and air traffic management systems. With capacity constraints already affecting several major UK airports, operators may face growing demands to expand terminals, improve operational efficiency and accommodate additional passenger and freight volumes over the coming decade.

The report also highlights challenges including airport congestion, labour shortages and rising operating costs. Aircraft delivery delays could further complicate growth plans by limiting the availability of new capacity.

According to Market Data Forecast, the sector's long-term outlook remains positive, although future growth will depend in part on the industry's ability to address infrastructure bottlenecks while meeting sustainability and operational requirements.
