What is a ferry or repo flight?

A ferry or repo flight is specifically defined as a flight that is conducted without any passengers on board. These flights are often necessary for repositioning an aircraft to its home base or to another location where it is needed, such as for maintenance or to pick up passengers or cargo. The primary purpose of a ferry flight is to operate the aircraft for logistical reasons rather than for carrying people.

While options related to cargo flights or crew-only flights might sound similar, they do not accurately capture the specific intent and nature of a ferry or repo flight, which focuses on the absence of passengers rather than the content of the flight.
