Which pricing method for international airfares depends on the specific route flown and is commonly used for international discount fares?

• A. Routing system
• B. Zone pricing
• C. Distance-based pricing
• D. Flat-rate pricing

Answer: (A)

Pricing that depends on the actual route flown centers on the precise path of travel—the origin, destination, and the specific airports and carriers used. This approach suits international discount fares because these fares are often restricted to certain routings; the price can change based on which route and connections you choose, even if the overall distance is similar. Different routes bring in different carriers, fare rules, and taxes, so the fare is tied to the exact itinerary. In contrast, zone pricing uses geographic bands, distance-based pricing uses mileage bands, and flat-rate pricing charges a single price regardless of route. So the method that explicitly ties price to the chosen route and is common for international discount fares is routing-based pricing.
