Who is referred to as a Jumpseat Rider?

The term "Jumpseat Rider" specifically refers to a non-working crewmember who has authorization to occupy a jumpseat in the flight deck or cabin during a flight. This can include off-duty flight attendants or pilots who are flying as passengers but have a special status that allows them to utilize these seats, which are typically reserved for crew members.

Jumpseat Riders are an integral part of airline operations, as they can provide support or assistance if needed in flights. They also help maintain a connection among crew members across different flights and can be useful for mutual aid in case of emergencies. Thus, the definition aligns perfectly with the role and function of someone traveling in a jumpseat, distinguishing them from regular passengers or actively working crew members.
