Grant Assurance #24 mandates that airports must establish fees to achieve what main goal?

Grant Assurance #24 focuses on ensuring that airports generate sufficient revenue to become as self-sustaining as possible. This means that airports are encouraged to develop fee structures that cover operational costs, maintenance, and necessary improvements without relying excessively on external funding.

The self-sustaining model is aimed at ensuring that airports can maintain their services and infrastructure without financial distress. This often involves establishing fair and reasonable fees for various services and facilities, thereby promoting financial responsibility and long-term sustainability. By achieving this goal, airports can better manage their resources, optimize operational efficiency, and be less dependent on taxpayer dollars or outside funding sources.

Other options, while they may touch on aspects of airport operations, do not capture the essence of Grant Assurance #24, which is primarily about the financial independence and operational sustainability of airports.
