Which is NOT a common incentive that airports provide to carriers?

The correct answer is associated with the practices airports typically engage in to attract and retain airlines. While airports often provide various incentives to carriers to encourage them to operate at their facilities, free fuel is not a standard or common incentive.

Airports might offer revenue guarantees or marketing and advertising support as a way to mitigate financial risks for airlines and enhance their visibility in the market. Likewise, fee waivers during promotional periods are a strategy that airports use to encourage new routes and additional flights, aiming to boost passenger traffic and revenue over time.

However, providing free fuel represents an unusually high level of support that airports do not typically offer. Fuel costs are generally borne by the airlines, and free fuel would introduce significant logistics and financial complications, potentially affecting the airport’s operations and budget sustainability. As a result, free fuel is not seen as a common incentive in the context of airport-carrier relationships.
