The Captain may authorize the use of all Flight Deck jumpseats, but only to authorized personnel. Non- CASS OAL personnel are excluded from riding in the Flight Deck jumpseat, but may ride in any available cabin seat. In addition, the Captain may authorize a qualified Flight Deck jumpseat rider to ride in an available main cabin seat and, in coordination with Flight Attendant #1, may authorize the use of a vacant additional cabin jumpseat for qualified personnel. The Captain has the authority to exclude any person from the Flight Deck in the interest of safety.Should a jumpseat rider physically occupy a cabin jumpseat, the Captain must be notified for approval and weight and balance purposes. The Captain’s approval is not required if a jumpseat rider is assigned a main cabin seat by the Gate Crewmember and is occupying the seat.• Note •The above guidance does not constrain the Captain from exercising Captain’s Authority and requiring jumpseat rider(s) with a cabin seat assignment to visit the Flight Deckduring the boarding process.
