Behind the Scenes: Troubled Cathay Pacific Flight - What Happened?

I follow the Cathay Pacific pilots and cabin crew for flight briefing before boarding the Boeing 777-300/ER to Paris. However, we encountered trouble before takeoff…What happened?

I boarded the flight early to film how Cathay's crew prepared for departure. While the pilots were checking, they discovered a mechanical fault on the B777. Engineers were called in for troubleshooting while all the passengers waited. Later, it was determined that the best solution was to change to another aircraft.

Luckily, Cathay found another 4 class B777-300/ER so all the catering, baggage, and cargo were moved to the new plane. All passengers and crew had to deplane and our departure was delayed by 2 hours. The efficiency of the airline operations was noted during the recovery process and we managed to depart without further issues or delays.

After takeoff, cabin crew started their busy duty on the 13-hour-long flight. They explained their workloads on the overnight intercontinental flight to me. Go behind the scenes to discover the inflight operation.
