American Express Membership Rewards points cannot be transferred to United MileagePlus. United has never been an Amex transfer partner, and there's no indication that's changing. If you want to fly United using Amex points, you have exactly two working options: book through the Amex Travel portal at a fixed redemption rate, or transfer your points to a Star Alliance partner program — Air Canada Aeroplan, ANA Mileage Club, Avianca LifeMiles, or Singapore Airlines KrisFlyer — and book the same United-operated flight through that program's award chart.

Can American Express Points Be Used for United Airlines?

Yes, just not by moving points directly into a MileagePlus account. Amex Membership Rewards has a fixed list of airline and hotel transfer partners, and United has never been on it — that's a permanent structural fact of the program, not a temporary gap. If you've seen conflicting information, it's likely because people conflate "transferring points to United" with "using points to fly United," which are very different things. The second is entirely possible through the Amex Travel portal or a Star Alliance partner transfer; the first is not and won't be.

United's own frequent flyer program only accepts transfers from Chase Ultimate Rewards and a small number of other issuer currencies. If flying United on transferred miles is your priority rather than a specific route or cabin, it's worth understanding which credit card points actually transfer to United MileagePlus before you commit to an Amex-heavy strategy.

Why United Isn't an Amex Transfer Partner

Airlines choose their card-transfer partners based on commercial deals, not convenience for travelers. United has built its transfer relationships around Chase, and Amex has built its Star Alliance access around Aeroplan, ANA, Avianca, and Singapore Airlines instead. Since United sits inside the Star Alliance network, a partner transfer still gets you onto the same physical aircraft, same cabin, same United crew — the miles just come from a different loyalty account, and the price in miles is set by whichever program's award chart you're redeeming from, not United's own chart.

How Amex Point Transfers Actually Work

Membership Rewards points live in a single pool tied to your Amex account, not to an individual card. Any card that earns Membership Rewards — Platinum, Gold, or a business equivalent — feeds the same balance, and you initiate a transfer from the Amex online portal or app by choosing a partner program and entering the loyalty number you want the points to land in. Most airline transfers post within minutes to a day; hotel transfers can be slower. Transfers are one-way: once points leave Membership Rewards, Amex will not move them back, and most partner programs won't reverse the transfer either. That's why the sequence matters — confirm the award seat exists in the partner program before you move a single point, not after.

The Two Real Ways to Use Amex Points on United Flights

1. Book United Through the Amex Travel Portal

Amex lets you redeem Membership Rewards points directly for United flights (and most other airlines) through its own travel portal, paying at a fixed cash-equivalent rate rather than an award chart. This works exactly like paying with a debit card that happens to be denominated in points: you see the cash fare, and your points cover it dollar-for-dollar at Amex's set rate. There's no need to search award space, no partner account to open, and no risk of the flight selling out of "award inventory" — if a seat is for sale, you can buy it with points. The tradeoff is that you're paying retail-equivalent pricing rather than an airline's often-cheaper miles-based award price.

2. Transfer to a Star Alliance Partner and Book United-Operated Flights

The alternative is moving points out of Membership Rewards into Aeroplan, ANA Mileage Club, Avianca LifeMiles, or Singapore KrisFlyer, then searching that program's own award chart for a United-operated flight. Because award pricing on these charts is often lower than what you'd pay through cash-equivalent portal redemptions — sometimes dramatically so on premium cabins — this is the route serious points travelers default to. The catch is that transfers are one-way and usually irreversible, so you should confirm real award seat availability on the flight you want before you transfer a single point.

Which Amex Transfer Partners Can Book United Flights

All four of these programs are Star Alliance members (or have an award-chart relationship with Star Alliance carriers) and can ticket United-operated flights. Each has meaningfully different rules around fuel surcharges, stopovers, and award chart structure.

Program	Transfer ratio from Amex	Award chart type	Fuel surcharges on United flights
Air Canada Aeroplan	1:1	Zone/distance-based	Generally none on United-operated segments
ANA Mileage Club	1:1	Distance-based	Avoided on most United awards
Avianca LifeMiles	1:1	Distance-based	Avoided on most United awards
Singapore KrisFlyer	1:1	Distance-based	Varies by route

Aeroplan tends to be the most flexible for one-way and multi-city United itineraries and has the largest English-language user community, which makes troubleshooting easier. ANA and LifeMiles are often cited for lower-mileage awards on certain United routes since neither charges fuel surcharges the way some European carriers do. KrisFlyer sits in between, with pricing that shifts more by route length than by cabin demand.

Full List of Amex Transfer Partners: Airlines, Hotels, and Other Programs

United's absence doesn't mean Amex points are limited — quite the opposite. As of September 2026, Amex transfers to sixteen airline programs, most at 1:1, plus a small number of hotel and non-airline partners. Here are the airline partners in full:

Airline program	Transfer ratio
Air Canada Aeroplan	1:1
ANA Mileage Club	1:1
Avianca LifeMiles	1:1
Singapore Airlines KrisFlyer	1:1
Air France/KLM Flying Blue	1:1
British Airways Executive Club	1:1
Iberia Plus	1:1
Qantas Frequent Flyer	1:1
Qatar Airways Privilege Club	1:1
Virgin Atlantic Flying Club	1:1
Delta SkyMiles	1:1
Aer Lingus AerClub	1:1
Aeromexico Club Premier	1:1.6
Cathay Pacific Asia Miles	5:4
Emirates Skywards	5:4
JetBlue TrueBlue	1:0.8

Hotel partners: Membership Rewards also transfers to Hilton Honors and Marriott Bonvoy. Hotel transfer ratios are typically less favorable than airline ratios, since hotel points are individually worth less — always check the live ratio shown in the Amex transfer portal before moving points, since hotel ratios move more often than airline ones and are not worth locking into memory.

Other partners: Amex periodically lists a small number of non-airline, non-hotel transfer options, and the exact roster varies by country and by which Amex card you hold. If you don't see a program you expect in your account, that's usually a market or card-eligibility restriction rather than an error — check the transfer menu inside your own Amex account rather than relying on a partner list from a different region.

Note that Etihad Guest was removed from the airline list permanently on 30 June 2026 — if you saw it listed on an older article, that transfer path no longer exists. If your real question is broader than United — for example whether Amex points work for Delta — that's covered separately in the Amex Membership Rewards transfer guide, and if Avios-earning partners like British Airways are more your interest, the Amex-to-Avios transfer bonus page covers current promotional ratios.

How Do I Book a United Flight With Amex Points?

The exact steps depend on which of the two routes you're using.

Decide your route first. Amex Travel portal redemptions make sense for short notice, sold-out award space, or simple domestic hops where the point value doesn't swing much either way. Partner transfers make sense for long-haul premium cabins, where award pricing can beat cash-equivalent redemptions by a wide margin.
If using Amex Travel: search United flights directly inside the Amex Travel portal, select the flight, and choose to pay with points at checkout. No transfer, no partner account, no award-chart guesswork.
If transferring to a partner: first confirm that a bookable award seat exists on your target United flight through Aeroplan, ANA, LifeMiles, or KrisFlyer's own search tool. Only after you've confirmed real availability should you initiate the Amex transfer, since it can't be reversed. Then complete the booking directly with that partner program, phone or online, depending on the carrier.
Watch mixed-cabin and multi-carrier itineraries. Some Star Alliance partners restrict which United fare classes are bookable on partner awards, especially in business and first class, so a flight showing "available" in cash doesn't always mean it's award-bookable through every partner.

Is It Better to Use Amex Travel or Transfer to a Partner?

There's no universal answer — it depends on cabin, route, and how much your time is worth. As a general framework:

Amex Travel portal wins when you want simplicity, when award space through partners doesn't exist for your dates, or when the cash fare is already low enough that a fixed per-point redemption rate isn't a bad deal.
Partner transfer wins when you're booking a premium cabin on a long-haul United route, where award charts frequently price out well below the cash-equivalent portal rate, assuming you can find the seat.

The deciding factor is almost always availability, not price theory. A partner transfer that saves money on paper is worthless if no award seat exists on the day you need to fly. For a broader breakdown of how to value a Membership Rewards point across all redemption paths — not just United — see how much an Amex point is actually worth.

Finding Star Alliance Award Availability Before You Transfer

This is the step most guides skip, and it's the one that actually determines whether the partner-transfer route works. Each Star Alliance program's own search tool only shows availability within its own network view, and United doesn't publish a single unified "partner award calendar" — so checking Aeroplan, then ANA, then LifeMiles, then KrisFlyer one at a time for the same United flight is slow and easy to get wrong, especially across multiple dates or cabins.

This is the exact problem Award Travel Finder is built for: it searches award availability across 40+ programs, including all four Amex Star Alliance partners, in one query, so you can see which program actually has a bookable seat on your United flight before you transfer a single point. It also values your Membership Rewards balance against each transfer option and maps out the transfer path itself, which matters more once you're juggling Aeromexico's 1:1.6 ratio or Cathay's 5:4 alongside straightforward 1:1 partners.

Best Amex Cards for Transferring to United Partners

Any Amex card earning Membership Rewards can feed these transfers — the points pool is shared across the whole card family. The differentiator is earning rate on the categories you actually spend in.

The Platinum Card from American Express

Platinum's earning structure is built around travel: it typically earns bonus points on flights booked directly with airlines or through Amex Travel, on top of the base rate on everything else. For someone planning to funnel points toward Aeroplan or ANA for United-operated award flights, the accelerated airfare earning is the main reason to hold the card over a no-annual-fee alternative — the tradeoff is a meaningfully higher annual fee that only pencils out if you use the travel credits and lounge access that come with it.

American Express Gold Card

Gold is generally the better everyday-spend earner, with bonus categories concentrated in dining and U.S. supermarkets rather than travel purchases. For a points strategy aimed at United redemptions, Gold works well as the card that stockpiles the balance day-to-day, while a separate purchase or transfer decision handles the actual booking. Many transfer-focused travelers hold both Platinum and Gold specifically to cover both earning patterns without splitting their Membership Rewards balance across issuers.

If you're deciding whether to build your United strategy around Amex-to-partner transfers or lean on Chase's direct United relationship instead, the Amex vs. Chase points comparison lays out the tradeoff in more detail than a card-by-card list can.

What About Alaska Mileage Plan Instead?

Amex doesn't transfer to Alaska Airlines Mileage Plan either, but it's worth a mention because Alaska has its own web of airline partnerships that occasionally undercuts Star Alliance pricing on certain United-operated routes booked through other means. If that's part of your research, the Alaska Mileage Plan transfer partner guide covers which currencies actually reach it and how it stacks up against the Star Alliance route to United.

Quick Answers

Can American Express points be used for United Airlines?

Yes, through the Amex Travel portal at a fixed redemption rate, or by transferring to Aeroplan, ANA, LifeMiles, or KrisFlyer and booking the United-operated flight through that program's award chart. Points cannot go directly into a MileagePlus account.

What airlines can I transfer Amex points to?

Sixteen programs as of September 2026, listed in full above, including four — Aeroplan, ANA, LifeMiles, and KrisFlyer — that can book United-operated flights as Star Alliance partners. Amex also transfers to Hilton Honors and Marriott Bonvoy.

How do I book a United flight with Amex points?

Either pay directly through the Amex Travel portal at a fixed rate, or transfer points 1:1 to Aeroplan, ANA, LifeMiles, or KrisFlyer after confirming award space, then book the United flight through that program.

Is it better to use Amex Travel or transfer to a partner?

Transferring usually wins on price for long-haul premium cabins if award space exists; the Amex Travel portal wins on simplicity and guaranteed availability whenever it doesn't.

Bottom Line

Amex Membership Rewards will never transfer directly to United MileagePlus — that's a permanent feature of how both programs are structured, not a gap that's likely to close. The practical path is either paying through Amex Travel at a fixed rate or transferring to one of four Star Alliance partners and booking the same United flight through their award chart. Which one wins for a specific trip comes down to whether award space actually exists on the date and cabin you want, which is worth checking across every partner before you transfer anything.
