Cathay Pacific today (31 October 2023) commenced using Boeing 777-300ER aircraft on Hong Kong / Perth services (CX171 / CX170), with B-KQU operating the first one tonight.
Previously, Cathay used Airbus A350-900 and A350-1000 aircraft on the route. A350-1000 B-LXN operated the final A350 service on 28 October 2023.
While the A350 is more popular with passengers for its quieter cabin, comfort and technology, in one of its configurations the 777-300ER has more seats.
