The final component of an airport's assessment is to determine ______.

• A. Leakage
• B. Demand
• C. Capacity
• D. Utilization

Answer: (A)

In airport market assessment, the last piece to quantify is leakage—the portion of potential demand that does not get served by the airport and instead moves to other airports or modes. This measure completes the picture by showing how much of the market’s travel needs are spillover rather than captured locally. If leakage is high, it means there’s unmet demand that could justify expanding capacity, adding routes, or improving services to attract more travelers. If leakage is low, the airport is capturing most of the local demand. The other concepts describe how big the market is (demand), what the facility can handle (capacity), and how much of that capacity is being used (utilization), but leakage tells you how much of the opportunity is slipping away to alternatives.
