Best Seats on the Cathay Pacific Boeing 777-300ER

Cathay's 777-300ER is the only aircraft carrying the new Aria Suite, and the fleet is mid-conversion: around 10 aircraft have it so far, with the whole long-haul 777-300ER fleet due to be reconfigured by late 2027. The rest still fly the Cirrus reverse herringbone, plus Cathay First on a small number of tails.
