I bet that airport traffic can either grow, shrink, or stay indifferent over time in real life (the same applies to some airports' infrastructure). This is why I need an 'automated air ticket pricing system', which calculates the pricing based on the destination airport's traffic level, which should range from $100 to $5,000 (the more crowded the airport, the lower the price, according to this system - for example, an air ticket for a route to Atlanta Hartsfield would cost $100, due to its traffic level of a 9).
Remember: this is not the current system. This is a proposal for a new, automated system that calculates route prices, depending on the traffic levels of destination airports.
