On the 777-300ER, what is the required minimum crew on a thru flight?

• A. 5
• B. 6
• C. 4
• D. 7

Answer: (A)

Two pilots in the cockpit plus three flight attendants in the cabin are needed to operate a 777-300ER on a thru flight. The two pilots handle flying the airplane, while the three flight attendants cover cabin safety duties, door supervision, passenger service, and readiness to respond in an emergency. This staffing level provides adequate coverage for all cabin areas, ensures there are enough crew to manage evacuations if needed, and meets the airline’s standard minimum for this aircraft on long or continuing itineraries.

Five crew members is the minimum because reducing to four would leave insufficient cabin supervision and door coverage, while six or seven would exceed the minimum staffing typically required for a thru flight on this aircraft.
