Airline alliances explained for points travelers

Most alliance explainers stop at "Star, oneworld, and SkyTeam exist," list the founding years, and leave you to figure out the actual booking implications yourself. Sixty seconds in you've forgotten which one Cathay is in and whether Lufthansa partners with United.

This post is different. It treats the three alliances as a working tool for award bookings: which airlines belong to each one, which loyalty programs you can actually reach from US credit card points, and which recent membership shifts (SAS leaving Star Alliance, ITA flipping from SkyTeam to Star, Hawaiian joining oneworld) actually change what's bookable from your wallet.

Why alliances matter when you're booking

When you redeem points on an alliance partner, you usually book through your home program's award chart. So a United MileagePlus account holder can book a Lufthansa, Singapore, ANA, or Turkish flight using United miles, all priced off the United partner award chart, not Lufthansa's or Singapore's. The Star Alliance plumbing is what makes that work.

This matters for points because:

1. Charts vary wildly across programs in the same alliance. ANA's First Class to Tokyo costs 85,000 Virgin Atlantic miles one-way (the canonical sweet spot, verified in our calculator). The same seat costs substantially more via United and via Aeroplan (both run higher partner-award rates with worse surcharge profiles). Identical cabin, identical flight. The points cost is set by whose chart you book through, not by the carrier you're flying.

2. Sweet spots almost always live in one specific program's chart. When you hear "use Avianca LifeMiles for Star Alliance business class," that's because Avianca's chart is cheaper than United's or Aeroplan's for that specific route. Knowing what alliance Avianca is in (Star) tells you which seat you can actually book with those LifeMiles.

3. Your credit card points connect to airline programs, not to alliances directly. Chase UR transfers to United (Star), Virgin Atlantic (independent), Flying Blue (SkyTeam), and so on. The alliance just tells you the inventory you can search through any of those programs.

Once you can hold all of that in your head, alliances stop being trivia and become a routing system. The diagram below is the cheat sheet.

The diagram

The diagram below is interactive. Pick a currency from the filter or drop balances into the URL (e.g. add ?chase_ur=100000&amex_mr=50000 to this page's address) and the cards highlight which airlines you can reach. Members with no US transferable path stay visible so you know what isn't bookable from a credit card wallet at all. Recently joined and exiting members carry small badges.

How to read this when you're planning a redemption

A few patterns that come up constantly in our user signals:

1. Pick the alliance before you pick the program. If you want a specific flight, say JFK to Tokyo on ANA, you don't start with "what's my best Chase UR redemption." You start with: ANA is Star Alliance. Which Star Alliance programs have the cheapest chart for that route? Virgin Atlantic (a SkyTeam carrier with a longstanding Flying Club bilateral that lets them book ANA premium cabins) is the famous answer at 85K miles for First Class. United and Aeroplan are Star-Alliance-internal alternates. From there, you map back: do any of those programs match a currency you actually hold? Chase UR transfers to Virgin Atlantic at 1:1, so the answer is yes.

2. Alliance reach beats single-program reach. Holding a balance in one Star Alliance program gives you booking access to all 26 Star carriers (currently), because the whole point of an alliance is partner award redemption: you book a Lufthansa, Singapore, or ANA flight using Aeroplan or United miles, priced off the issuing program's partner chart. The carrier you fly and the program you redeem are decoupled. Same logic in oneworld and SkyTeam. This is why a single transferable currency that reaches even one strong program in each alliance (like Chase UR reaching United + BA + Virgin Atlantic + Flying Blue + Aeroplan) gives you genuinely broad redemption coverage.

3. The independents are not alliance partners, they're a separate booking system. Emirates, Etihad, JetBlue, and Southwest don't participate in any alliance. They run their own loyalty programs with their own partners (Etihad and JetBlue have a deep bilateral partnership now; Emirates partners with Qantas across both networks, especially the Dubai-Australia routings, and ran a JetBlue tie-in that's being wound down; Southwest historically had no interline partnerships at all and added their first-ever, Icelandair, in 2025). When someone says "transfer Capital One to Emirates Skywards for First Class," that's a non-alliance booking using Emirates' own chart, not an alliance redemption. The fact that Emirates is independent doesn't make it worse, it just means routing logic doesn't apply.

4. The Aer Lingus caveat (and a few like it). Aer Lingus participates in oneworld with limited benefits, not as a full member: they're owned by IAG (the same parent as BA and Iberia), so you can usually book Aer Lingus award space using American AAdvantage, British Airways Avios, Alaska Mileage Plan, or Iberia Avios. But you can't earn or burn AerClub Avios on most oneworld carriers the way you can with full members like AA or BA. We tag programs like this so you don't assume full alliance behavior.

Recent changes that matter (2023 to 2026)

Alliance membership doesn't shift often, but when it does, redemption math can flip overnight. The shifts worth internalizing:

• SAS left Star Alliance for SkyTeam on September 1, 2024. EuroBonus points used to be excellent for Star Alliance redemptions, and SAS's elite status earning was a famously easy path to Star Alliance Gold. That's all gone. EuroBonus is now a SkyTeam program with Air France, KLM, Delta, Korean Air, and Virgin Atlantic as its partners. Pre-existing award bookings issued before August 31, 2024 were honored after the cutover, but new EuroBonus-funded Star Alliance bookings stopped on August 31, 2024.

• Virgin Atlantic joined SkyTeam on March 2, 2023. First UK SkyTeam carrier. Flying Club still maintains its big bilateral partnerships (ANA, Delta, Singapore via the older agreements), but Virgin Atlantic flights are now bookable via SkyTeam members' charts in addition to Flying Club's own. This makes Delta SkyMiles and Air France Flying Blue more useful for Virgin Atlantic redemptions than they used to be.

• Hawaiian Airlines joined oneworld on April 22, 2026. A consequence of the Alaska + Hawaiian merger (closed October 2025). HawaiianMiles converted into Atmos Rewards (Alaska's combined loyalty) on October 1, 2025. Hawaiian's HA flight code is being phased out and flights are migrating to AS metal over the next year. For US travelers this means Hawaiian inventory is now bookable using any oneworld currency you'd use for Alaska. Cathay points (formerly Cathay Asia Miles, rebranded into a single Cathay membership in 2022) is one of the strongest sweet spots for West Coast to Honolulu redemptions because Cathay's chart runs dramatically below US-carrier rates on that route, and the same Cathay chart now applies to legacy Hawaiian-operated flights.

• ITA Airways switched alliances. Left SkyTeam on April 30, 2025. Joined Star Alliance on April 1, 2026 as the 26th active member. The Italian carrier's small loyalty program (Volare) was replaced by Lufthansa's Miles & More. For US points travelers this is mostly a fact to file away because ITA doesn't have a direct transferable-currency path, but it does mean ITA award space is now bookable via United or Aeroplan rather than Delta or Flying Blue.

• Oman Air and Fiji Airways joined oneworld in 2025. Both are interesting but neither has a direct US transferable path yet. Oman Air joined June 30, 2025; Fiji Airways joined March 31, 2025. Worth knowing if you're routing through OMA or NAN.

• Asiana is leaving Star Alliance in late 2026. Korean Air completed its acquisition of Asiana in December 2024; the Asiana brand sunsets on December 17, 2026, after which Asiana routes fold into Korean Air's SkyTeam membership. Asiana award bookings are increasingly restricted as the transition runs out.

Why this diagram exists on Points Radar specifically

We built Points Radar to answer "what can I actually book with the points I have." Alliances are the substrate that determines which sweet spots are reachable from which transferable currency. When you load the radar with balances, every card you see reflects an alliance routing decision we've already made for you. If you ever want to see why a given card lights up, the diagram above is the picture under the calculator's math.

If you're new here, the natural next step is entering your balances and seeing the wall. If you're a more advanced traveler trying to plan a specific redemption, each of the currency landing pages walks through the partner list for your issuer with the same alliance framing applied. For the cross-cutting view (which programs every US card transfers to, side by side, with live bonuses flagged) see the transfer partners matrix.
