Cathay Pacific is Hong Kong's flag carrier and a oneworld founder, while Asiana Airlines is a South Korean full-service carrier in Star Alliance. Travellers compare them mainly on Hong Kong–Seoul Incheon, which both serve, and on onward trips between Asia, North America and Europe. Korean Air is due to absorb Asiana on 17 December 2026, which changes what booking it means.
Quick verdict
Both are full-service airlines, so the choice comes down to hub, alliance and timing. Cathay suits travellers starting in Hong Kong or connecting through it, and those who want oneworld benefits or a First class option on some 777-300ERs. Asiana suits travellers who want to connect through Seoul Incheon on Star Alliance, but anyone booking beyond 17 December 2026 should check which airline will operate the flight.
Choose Cathay Pacific if…
- You are flying from or via Hong Kong, Cathay's sole hub, with a network of more than 190 destinations including codeshares.
- You collect oneworld miles or Marco Polo Club status, with lounge guest access at Diamond and Gold tiers.
- You want Cathay's refurbished cabins: refurbished 777-300ERs have Aria Suites and a new Premium Economy.
Choose Asiana Airlines if…
- You want to connect through Seoul Incheon or Gimpo, or reach Jeju, on one Star Alliance ticket.
- You want a First Suite on the A380 or the Business Smartium cabin, where the aircraft flies your route.
- You are happy to book a near-term trip, and will check the operating airline if travelling after the December 2026 merger.

Key differences
Network and hubs
Cathay Pacific operates from a single hub, Hong Kong International Airport, and with subsidiaries and codeshares serves more than 190 destinations in over 60 countries. Asiana flies from Seoul Incheon and Gimpo, with Jeju as a focus city, to about 78 destinations across Asia, North America, Europe and Oceania. Both serve Hong Kong to Seoul Incheon, so that route is a straight comparison. Beyond it, choose by which hub fits your onward connection.
Merger and brand status
Asiana still flies under its own brand, but ch-aviation reports that both boards approved a merger agreement on 13 May 2026. Korean Air is due to absorb Asiana's assets, liabilities and employees on 17 December 2026, and the Asiana brand is expected to be phased out gradually. Cathay has no comparable change. If your flight is after that date, check who operates it and whether Star Alliance and mileage rules apply as booked.
Cabins and seats
Cathay offers Business, Premium Economy and Economy, with First on some Boeing 777-300ER aircraft. Refurbished 777-300ERs have the new Aria Suites and Premium Economy, and A330s are due to be refitted with Aria Studio and new Economy seats. Asiana lists five classes: First Suite (flown on the A380), First, Business Smartium, Business and Travel (economy). Its six A380s are due to be retired before 2030. Both vary by aircraft, so check the seat map for your flight.
Fleet
Cathay operates 159 passenger aircraft plus 20 Boeing 747 freighters (December 2025): A321neo, A330-300, A350-900 and -1000, and 777-300/300ER. It has 35 Boeing 777-9 on order, with deliveries from 2027. Asiana has 67 aircraft in service and 27 on order (October 2026), including A321, A330-300, A350-900 and 777-200ER. Cathay has the larger fleet, while Asiana's is smaller.
Loyalty, alliances and lounges
Cathay is a oneworld founder. Its Marco Polo Club gives lounge access by tier: Diamond members may bring two guests, Gold one, and Silver members enter alone. In Hong Kong, business passengers use The Wing, The Pier or The Deck, and a redesigned The Wing was announced in April 2026. Asiana is in Star Alliance, and its Asiana Club has five tiers: Silver, Gold, Diamond, Diamond Plus and Platinum. Its programme is expected to be merged with Korean Air's, so mileage rules may change.
Reliability
Cirium data reported by the South China Morning Post gave Cathay a 78.13% on-time arrival rate in April 2025, ninth among Asia-Pacific airlines. Cathay also reported 11% more passengers in January 2026 than a year earlier. For Asiana, Flight OZ214, a Boeing 777-200ER, crashed on landing at San Francisco in 2013. Check recent punctuality for your specific route before booking.
