oneworld Airlines 2026: Full Member List and How to Book

oneworld is the alliance behind American, Alaska, British Airways, Cathay Pacific, Qatar, and Japan Airlines. It's smaller than Star Alliance, but it has some of the best business class products out there, and lots of bank points can reach it. Here's who's in it, who isn't, and how I'd think about booking it.

Last updated: November 9, 2026

Quick answer: Cathay Pacific, Japan Airlines (JAL), and British Airways are all in oneworld. None of them are in Star Alliance or SkyTeam.

If you landed here because you searched "Cathay Pacific Star Alliance," you're not alone. It's one of the most common mix-ups, and the answer is no. Cathay is oneworld.

New to alliances? Read my alliances explainer first.

oneworld members

oneworld itself says it has 15 member airlines, because it counts Alaska and Hawaiian together as one. I've listed them separately since people search for each one. Hawaiian joined in April 2026, and Alaska joined in 2021. The two now share one loyalty program, Atmos Rewards. Fiji Airways and Oman Air are full members too, which surprises a lot of people.

Philippine Airlines has signed up to become oneworld's next member. It isn't in yet. oneworld announced the deal in June 2026, and the airline has said joining in the second half of 2027 is realistic. oneworld also notes that S7 Airlines' membership has been suspended since April 2022, so I've left it off the list.

Not in oneworld

A few of these trip people up. LATAM left oneworld in 2020 and hasn't joined another alliance. It works closely with Delta instead. Aer Lingus is owned by the same group as British Airways and Iberia, but it left oneworld in 2007. Emirates and Etihad have never joined an alliance, and I explain how Emirates works in which alliance Emirates is in.

Best programs for booking oneworld flights

These are the oneworld programs I'd check first, with the bank points that transfer to them:

Ratios aren't always 1:1. Amex sends fewer miles to Cathay Pacific than points you transfer. Capital One sends Japan Airlines Mileage Bank 1.5 miles for every 2 points. Citi's ratios depend on your card, and its no-annual-fee cards get less than its premium cards on every partner. Check your issuer's transfer screen before you move anything, because transfers are usually final.

Several programs use Avios (British Airways, Iberia, and Qatar), so it's worth pricing the same flight in more than one of them. For flights to Asia, Cathay Pacific Asia Miles and JAL Mileage Bank are the two I'd look at first. If you have Citi points and want JAL's business class, my Citi to JAL walkthrough goes step by step. Citi is the only one of the four big banks that transfers to American AAdvantage. Atmos Rewards isn't on the Amex, Chase, Citi, or Capital One lists, so you'd earn it by flying or with a co-branded card.

I haven't quoted award prices on this page because I'm only using numbers from official award charts, and I haven't pulled those charts for oneworld programs yet. Check the program's own award calculator before you transfer.

Finding the seats

Start with the airline that actually flies your route, then search a couple of the programs above for the same flight. My guide on how to search for award flights walks through it.

To see award space across lots of programs at once, I use Seats.aero. I get commissions for purchases made through links in this post. Search Seats.aero

Planning a stop in Doha or Hong Kong on the way? My guide to award stopovers and open jaws covers how that works.
