Airport prices are generally higher due to a number of factors, including:

Convenience: Airports are often located in convenient locations and offer a variety of services, making them more attractive to customers who are willing to pay more for the convenience.

Limited competition: The limited competition at airports, combined with the captive audience of travelers, allows businesses to charge higher prices.

Operating costs: Operating an airport is expensive, and businesses must cover these costs through higher prices for goods and services.

Taxes and fees: Airports often charge various taxes and fees, which are passed on to consumers in the form of higher prices.

Brand premium: Some airport businesses offer premium products and services that are more expensive than similar products and services available outside the airport.
