What term describes the fare for a trip through a connecting city when the flights involve different airlines that have agreed on one published fare?

• A. Mileage System
• B. Neutral Units of Construction (NUCs)
• C. Joint Fare
• D. Nonstop Flight

Answer: (C)

Joint fare is the price that two or more airlines publish for a single itinerary that includes travel on different carriers, typically with a connection in a transfer city. When airlines have interline or partnership agreements, they can set one published fare that covers the entire trip, even though you’re flying on more than one airline. This makes it easier to book and price multi-carrier itineraries with a single ticket and a unified fare rules structure.

For contrast, a mileage system relates to earning or redeeming miles, not the price of a multi-carrier trip. Neutral Units of Construction are a pricing unit used to convert currencies on international fares, not the fare type itself. A nonstop flight describes a flight with no connections, which doesn’t involve combining different carriers under one published fare.
