Which incentive is considered the primary desired incentive in Air Service Development?

The primary desired incentive in Air Service Development is minimum revenue guarantees. This type of incentive is crucial because it provides airlines with a level of financial security when they consider initiating or expanding service to a new market. By guaranteeing a minimum level of revenue, airports can effectively reduce the financial risk to airlines. This assurance can motivate airlines to launch new routes or increase frequency on existing routes, as they know that their basic operating costs will be covered even if initial passenger numbers are lower than expected.

In contrast, while fee waivers, discounted parking fees, and media promotions can also attract airlines, they typically do not offer the same level of financial security as a minimum revenue guarantee. Fee waivers may alleviate some operational costs but do not ensure revenue stability; discounted parking fees can benefit airport users but are less effective in convincing airlines to start a service; and media promotions help raise awareness but do not address the fundamental financial risks faced by airlines. Therefore, minimum revenue guarantees stand out as the most effective incentive for encouraging air service development.
