Booking a flight to Hong Kong isn't what it used to be. Things changed. Honestly, the way Cathay Pacific American Airlines operate together is one of those "open secrets" that most travelers barely scratch the surface of, even though it basically dictates how much you pay for a lie-flat bed over the Pacific.
You’ve probably seen both logos on a single ticket before. That’s codesharing. It’s a massive web. But if you’re just looking at the flight numbers, you’re missing the actual value.
The Oneworld Glue Holding Them Together
Cathay Pacific and American Airlines are founding members of the Oneworld alliance. This isn’t just some marketing badge. It means their systems are supposed to talk to each other, though anyone who has tried to change a seat assignment on a BA-issued ticket for a Cathay flight knows "talking" is a generous term.
The partnership exists because American Airlines needs a gateway into Asia that isn't Tokyo, and Cathay Pacific needs a way to fill planes from cities like Charlotte or Phoenix where they don’t fly their own green-and-white birds.
It's a symbiotic relationship. One provides the massive US domestic network; the other provides the gold-standard long-haul service.
Why the "Metal" Matters
When you book through the American Airlines website, you might see "Operated by Cathay Pacific." This is the "metal." If you have the choice, you almost always want to be on Cathay metal. American’s Flagship Business is solid—don't get me wrong—but Cathay’s service is just... different. It's more intuitive.
I remember a flight from JFK where the purser knew I liked sparkling water before I even asked for a refill. That’s the Cathay touch. American is getting better, especially with their new Flagship Suite seats rolling out on the 721XLRs and retrofitted 777s, but they are playing catch-up to the Hong Kong standard.

Earning and Burning: The Miles Game
Here is where people get tripped up. You can earn American Airlines AAdvantage miles on Cathay Pacific flights. But—and this is a big but—the rate at which you earn depends on the "marketing carrier."
If you buy the ticket through AA.com with an AA flight number, you earn miles based on the price of the ticket. If you book through Cathay’s site with a CX flight number, you earn based on the distance flown and the fare class.
- The Pro Tip: If you found a cheap economy ticket, book it as an AA codeshare to get those Loyalty Points based on spend.
- The Alternative: If it’s a pricey business class fare, booking it as a Cathay flight number often nets you way more miles because the distance from LAX to HKG is massive—over 7,200 miles.
Redemption Sweet Spots
American Airlines miles are arguably more valuable for flying Cathay Pacific than Cathay’s own "Asia Miles" are in certain scenarios. Why? Because American doesn't pass on those massive fuel surpluses that other airlines love to tack on.
Finding the space is the hard part.
Cathay Pacific is notorious for releasing "last minute" award seats. If you are looking 331 days out, you might see nothing. Check again 14 days before departure. Suddenly, the floodgates open. It's a stressful way to plan a vacation, but it’s how you get a $12,000 First Class seat for 110,000 miles and about $40 in taxes.
What Most People Get Wrong About Transpacific Transfers
Hong Kong International Airport (HKG) is the fortress. If you are flying American Airlines from Dallas (DFW) and connecting to a Cathay flight in HKG, your bags should go all the way through.

Usually.
Always double-check the tag. I’ve seen enough "mishandled" bags at the transfer desk to know that even the best systems glitch. The beauty of the Cathay Pacific American Airlines partnership is the protection. If your AA flight is delayed into Hong Kong, Cathay is contractually obligated to put you on the next available flight. If you booked these on separate tickets? You’re on your own. Don't do that. It's not worth the $100 you might save.
The Lounge Situation: Where the Magic Happens
If you have Oneworld Emerald status—maybe you hit it through American’s Executive Platinum tier—you have hit the jackpot in Hong Kong.
Cathay Pacific’s lounges, specifically "The Pier" and "The Wing," are widely considered the best in the world. We’re talking about a noodle bar, a dedicated tea house, and private "Day Suites" where you can nap overlooking the tarmac.
American Airlines Admirals Clubs are... fine. They have cheese cubes and hummus. But if you are an AA flyer in HKG, you don't go to the AA-associated partner lounges if you can help it. You go to The Pier.
Access Rules for the Average Traveler
- Business Class Passenger: You get into the Business Class lounges (The Deck, The Pier Business) regardless of which airline issued the ticket.
- AA Executive Platinum / Platinum Pro: You get into First Class lounges.
- AA Platinum: You get into Business Class lounges.
It's one of the few perks where the "American Airlines" loyalty actually pays off better abroad than it does at home.

The Reality of Hong Kong’s Recovery
We have to talk about the elephant in the room. Cathay Pacific had a rough few years. The pandemic hit them harder than almost any other carrier because they have no domestic market. None. You can’t fly from one side of Hong Kong to the other.
Because of this, flight frequencies between the US and HKG aren't back to 2019 levels yet. American Airlines has been slower to return to HKG with its own planes, often preferring to just put people on Cathay’s flights.
This means seats are tighter. Prices are higher.
Practical Steps for Your Next Trip
Stop searching for "flights to Hong Kong" on Google Flights and just picking the cheapest one. Use the tools available to actually maximize this partnership.
- Check the "Sold As" label. If you are an AA elite looking for Loyalty Points, ensure your flight has an AA flight number. If you are just looking for the best experience, prioritize "Operated by Cathay Pacific."
- Use British Airways' website to find award space. It sounds counterintuitive, but the BA search engine is often better at "seeing" Cathay Pacific award seats than American’s site is. Once you find the seats on BA, go back to AA.com or call them to book using your AA miles.
- Mind the terminal at JFK. If you’re connecting from an American flight to a Cathay flight at JFK, you’re changing terminals. You have to take the AirTrain. It takes longer than you think. Give yourself three hours, minimum.
- Download both apps. You’ll need the American app for your first leg and the Cathay app to manage your meal preferences or see the local gate info in Hong Kong. They don't always sync perfectly.
The partnership between Cathay Pacific and American Airlines is a pillar of global travel. It’s not perfect. The IT systems feel like they were built in 1995. But in terms of getting from the US to Asia with a bit of dignity intact, it’s still the gold standard.
Focus on the metal, watch the codeshare numbers, and always, always go to the noodle bar in Terminal 1.
