What is a ferry flight?

A ferry flight refers to a flight that is conducted without revenue passengers on board. These flights are typically utilized to reposition aircraft, allowing them to be moved from one location to another for a variety of reasons, such as taking a plane to a different airport for scheduled maintenance, repairs, or to meet operational demands. Since there are no paying passengers onboard, these flights often help airlines efficiently manage their fleet and ensure that aircraft are available where they are needed most.

While the other options describe valid flight scenarios, they do not encapsulate the primary definition of a ferry flight. A flight for maintenance purposes could be a ferry flight, but not all ferry flights are specifically for maintenance. Cargo-only flights and routine training flights also do not fit the definition, as they serve different operational purposes. Therefore, the essence of ferry flights revolves around the absence of revenue passengers while fulfilling operational needs.
