Abstract
Air navigation service providers fund their operations almost entirely through activity-based user charges, creating a structural dependency between revenue and air traffic volume. When traffic collapses, revenue falls immediately, but the cost base, dominated by specialised labour under fixed-term employment contracts and long-lived capital infrastructure, adjusts slowly, if at all. This paper examines how five corporatised, wholly government-owned air navigation service providers in the southern Asia-Pacific (i.e., Airservices Australia, Airways New Zealand, AirNav Indonesia, NiuSky Pacific in Papua New Guinea, and Fiji Airports) responded to the extreme demand shock of the COVID-19 pandemic and assesses the role of government grants in sustaining their financial viability. Drawing on eleven years of audited annual report data (2015 to 2024/25) and nine semi-structured interviews, the paper uses the Cost Flexibility Ratio, the proportional change in expenses relative to the proportional change in revenue, to quantify cost stickiness across five structurally diverse providers. Revenue from charges fell between 38% and 70% from the 2019 peak to the 2021 trough; expense reductions ranged from near-zero to moderately flexible. The findings identify labour contractual arrangements, investment cycle timing, and pricing freeze duration as the principal determinants of financial resilience. Recovery trajectories diverged sharply: three air navigation service providers returned to or exceeded pre-pandemic revenue levels by 2024, while Airservices Australia remained in deficit despite near-full revenue recovery. The results have implications for the design of air navigation service providers’ financing frameworks and government grant conditionality in regions with high demand volatility.
