During Part 121 flights, the exception allows a non-PIC occupant of a cockpit seat under what condition?

• A. No one else may occupy a pilot seat
• B. A student pilot may occupy a pilot seat under supervision
• C. At the discretion of the Captain, a qualified JetBlue pilot may occupy a pilot seat in cruise
• D. A flight attendant may occupy a pilot seat

Answer: (C)

Part 121 operations include an explicit exception that allows a non-PIC to occupy a cockpit seat, but only under a specific condition: the Captain must exercise discretion, and the occupant must be a qualified JetBlue pilot. This keeps the flight’s command structure intact while enabling a capable pilot to sit in the cockpit during cruise when additional relief or support is needed. The non-PIC occupant would not act as Pilot In Command; the Captain remains responsible for the flight. This only applies in cruise, not during takeoff or landing or other critical phases, and it excludes flight attendants and student pilots from this role.
