Which of the following is a synonym for "carrier" in the context of aviation?

In the context of aviation, the term "carrier" primarily refers to an airline, which is a company that provides air transport services for passengers and cargo. Airlines are responsible for operating flights and managing the logistics related to air travel, including ticket sales, scheduling, and aircraft maintenance.

The other options do not fit the same role: while "flights" refer to the actual journeys taken by aircraft, "airport" denotes a physical location where flights are operated, and "destination" signifies the endpoint of a flight rather than the entity responsible for conducting it. Thus, "airline" is the term that correctly aligns with the meaning of "carrier" in this context.
