Diversification - airports (aero vs non-aero)
What it is
Aeronautical revenue comes from regulated charges on airlines and passengers; non-aeronautical comes from retail, duty free, food and beverage, advertising, parking, lounges and real estate
Non-aero is unregulated, higher-margin and the primary source of value creation at a modern airport
Impact on industries
- Non-aero revenue is unregulated, so it is where operators earn returns above the allowed aeronautical rate
- It scales with passenger affluence and dwell time rather than with aircraft movements, so it grows faster than traffic
- Airport operator growth of 18-20% in FY26 was driven by traffic, tariff revisions and non-aeronautical expansion together
- Requires terminal space, tenant mix skill and retail management - competencies closer to mall operation than infrastructure
- Under hybrid till a share of non-aero still offsets aeronautical tariffs, so the regulatory model determines how much upside the operator keeps
