How does a routing system determine international airfare?

The selection of fixing prices based on the specific route taken accurately reflects how international airfare is determined by routing systems. Airfare pricing is influenced significantly by the specific origins and destinations of a flight, including the demand for specific routes, the operating costs associated with those routes, and the competition between airlines on similar paths.

Airlines assess a variety of factors when establishing fares, including the distance, but the routes themselves play a crucial role in pricing. Each route may have unique characteristics such as market competition, passenger demand, and specific regulations that can affect pricing strategies.

While comparing prices across various airlines may be part of the decision-making process for travelers, it is not the mechanism through which the routing system itself sets airfares. Similarly, flat rates do not accurately account for the variability in distance and demand that influences pricing for different journeys. Assessing the distance between two cities also plays a role but is typically part of a broader analysis that includes multiple factors influencing fare determination along a specific route. Therefore, the specific route taken encompasses the complexities of airline pricing strategy in international travel.
