Cathay Pacific Aria Suite: Which Aircraft and Routes Have It

The Aria Suite is Cathay Pacific's newest business class: a 1-2-1 suite with a sliding privacy door, a 24-inch 4K screen and wireless charging. It is the best business seat Cathay has made. It is also still rare: it is fitted to around 10 aircraft, all of them Boeing 777-300ERs, with the rest of the fleet still flying the older Cirrus reverse-herringbone seat.

Cathay sells both as the same business class fare. Whether you get an Aria Suite comes down to which aircraft operates your flight.

Which Cathay aircraft have the Aria Suite

Boeing 777-300ER, and only that. Around 10 aircraft have been converted so far. Cathay plans to reconfigure its whole long-haul 777-300ER fleet by late 2027, so the share will keep rising, but for now most 777-300ERs still have Cirrus.

Not the A350. Cathay's A350-900 and A350-1000 fleets fly the Cirrus reverse-herringbone seat across the board, and Cathay has no firm plans to bring the Aria Suite to them. If your flight is an A350, you will not get an Aria Suite.

Which routes have the Aria Suite

The Aria Suite launched on San Francisco in early 2026, followed by Los Angeles (CX880/CX881) from April 2026. Beyond that, the converted 777-300ERs move around the network: the same flight number can get an Aria Suite aircraft one day and a Cirrus 777 or an A350 the next.

Here is a real example from SeatRadar's data in early October 2026. Over its last 14 flights, half the aircraft seen on CX250 (London Heathrow to Hong Kong) had the Aria Suite and half had Cirrus. Over the same period, every one of the last 15 flights on CX251 in the other direction had Cirrus. Same route and the same aircraft type, but a very different chance of getting the new seat depending on which flight you book.

That is why "Aria Suite routes" lists go out of date fast. What matters is how often your specific flight number has had a converted aircraft recently.

Aria Suite vs Cirrus: is it worth chasing?

Cirrus is still a good business class: fully flat, 1-2-1, and every seat has direct aisle access. What the Aria Suite adds is a door, a much bigger and sharper screen, and a more modern suite. On a long overnight flight the door and privacy are the difference most people notice. If you have a choice of flights at a similar price, choose the one that runs the Aria Suite more often.

Best seats in the Aria Suite

Window seats 1A, 1K, 11A and 11K are the pick of the cabin. Avoid 6D and 6G. On the Cirrus 777-300ER, 11A, 11K, 17A and 17K are good choices and 12E/12F are the ones to skip.

How to pick a flight with the Aria Suite

1. **List the Cathay flight numbers** on your route, including the return and alternatives on nearby days.
2. **Look each one up on SeatRadar** to see how often it has had an Aria Suite 777-300ER over the last 14 days.
3. **Book the flight number with the highest Aria Suite share**, and avoid any that are mostly A350s.
4. **Re-check in the days before departure**, when the aircraft usually firms up.
