What is a "through fare" in the context of airline travel?

In airline travel, a "through fare" refers to the fare that covers a journey involving connecting flights on the same airline or its partners without requiring the passenger to purchase separate tickets for each segment. This means that when you book a ticket on one airline that involves one or more layovers or connections, you are getting a single fare that includes all segments of your journey, ensuring that your bags are typically checked through to your final destination and providing other conveniences associated with a seamless travel experience.

This concept is particularly important for travelers who may need to change planes at one or more airports, as it simplifies the process and often offers better pricing compared to booking individual legs separately. Understanding through fares is essential for travel agents as they help clients find the most efficient and cost-effective travel options.

In contrast, the other options mention scenarios that do not align with the definition of a through fare; for instance, round trips with different airlines, including various taxes and fees, or direct flights only do not encapsulate the essence of what a through fare entails in the context of connecting flights on a single airline.
