Quick Verdict
How to Transfer Amex Points to United Airlines ? You cannot transfer American Express Membership Rewards points directly to United Airlines MileagePlus United is not an Amex transfer partner.
However, you have two practical workarounds: transfer your Amex points to Air Canada Aeroplan or Avianca LifeMiles and then redeem those miles on United-operated flights, or convert Amex points to Chase Ultimate Rewards via a physical card product switch (not directly possible, but achievable through credit card strategy). This guide walks you through every option available in 2026 so you can maximize your Amex points for United flights.
Why You Can’t Transfer Amex Points Directly to United MileagePlus
United Airlines MileagePlus is not listed among American Express’s 21+ airline transfer partners as of April 2026. This surprises many travelers who assume all major U.S. carriers are Amex partners, but that’s not the case. United has a historically close relationship with Chase Ultimate Rewards, which remains the primary bank-issued rewards currency that transfers 1:1 directly into MileagePlus. Amex has built strong partnerships with Star Alliance carriers like Singapore Airlines KrisFlyer and Air Canada Aeroplan, but United itself is absent from the list. Understanding this limitation is the first step toward finding a smart workaround.
The good news is that United is a member of the Star Alliance, which means several Amex transfer partners can book United-operated award flights. This creates an indirect path that, with the right approach, can still deliver tremendous value sometimes even better redemption rates than booking directly through MileagePlus.
Amex’s Airline Transfer Partners at a Glance (2026)
Before diving into the workarounds, it helps to see the full landscape of Amex Membership Rewards transfer partners in 2026. The table below shows the key airline partners and their transfer ratios.
American Express Membership Rewards Airline Transfer Partners (2026)
| Airline Program | Alliance | Transfer Ratio (Amex:Miles) | Can Book United Flights? | Transfer Time |
| Air Canada Aeroplan | Star Alliance | 1:1 | Yes | Instant – 24 hrs |
| Avianca LifeMiles | Star Alliance | 1:1 | Yes | Instant – 24 hrs |
| Singapore Airlines KrisFlyer | Star Alliance | 1:1 | Yes (limited) | 1–3 business days |
| ANA Mileage Club | Star Alliance | 1:1 | Yes (limited) | 2–5 business days |
| Delta SkyMiles | Delta SkyMiles | 1:1 | No | Instant – 24 hrs |
| British Airways Avios | Oneworld | 1:1 | No | Instant – 24 hrs |
| Air France/KLM Flying Blue | SkyTeam | 1:1 | No | Instant – 24 hrs |
| Iberia Plus | Oneworld | 1:1 | No | 2–4 business days |
As you can see, the two standout options for booking United flights are Air Canada Aeroplan and Avianca LifeMiles. Both transfer at a 1:1 ratio from Amex meaning 10,000 Amex points become 10,000 miles in each program and both allow you to search for and book award seats on United-operated flights. Let’s explore each option in detail.
Option 1: Transfer Amex Points to Air Canada Aeroplan and Book United Flights
Air Canada Aeroplan is widely considered the best workaround for using Amex points on United flights. Aeroplan is a Star Alliance member, and United publishes award availability to Aeroplan just as it does to its own MileagePlus members. The transfer ratio is 1:1, and transfers typically clear within 24 hours sometimes instantly.
Step-by-Step: Transfer Amex Points to Aeroplan
Follow these steps carefully to complete your transfer and book a United award flight:
Step 1 : Log in to your Amex account.
Go to americanexpress.com and sign in. Navigate to the “Membership Rewards” section, which is typically found under the “Rewards” tab on your account dashboard.
Step 2 : Select “Transfer Points.
Inside Membership Rewards, look for the option that says “Transfer Points to Travel Partners.” Click it. You’ll see a full list of airline and hotel partners.
Step 3 : Choose Air Canada Aeroplan
Scroll through the airline partners and select “Air Canada Aeroplan.” You’ll be prompted to enter your Aeroplan membership number. If you don’t have an Aeroplan account yet, sign up for free at aircanada.com it takes about five minutes.
Step 4 : Enter the number of points to transfer.
You must transfer in increments of 1,000 points. Enter the amount you need for your award booking, keeping in mind that Aeroplan’s award chart requires specific mile amounts depending on your route.
Step 5 : Confirm the transfer.
Review your transfer details and confirm. You’ll receive an email confirmation from Amex, and the miles typically appear in your Aeroplan account within a few hours.
Step 6 : Search for United award availability on Aeroplan.
Log in to your Aeroplan account and use their flight search tool. Search for your desired route and filter for “United Airlines” in the carrier options. Aeroplan will display available United award seats.
Step 7 Book and pay taxes.
Select your preferred flight and complete the booking. You’ll pay a small amount in taxes and fees typically $5.60 per segment for domestic U.S. flights, though international routes may carry higher carrier fees.
Aeroplan Award Rates for United Flights (2026)
Aeroplan uses a distance-based chart for partner awards. Here are some common redemption benchmarks for United-operated flights in 2026: a short-haul domestic round trip in economy typically starts at 15,000–25,000 Aeroplan miles, while a transatlantic business class award can run 55,000–75,000 miles one-way. Compared to MileagePlus’s own dynamic pricing which in 2026 can demand 80,000+ miles for the same business class seat Aeroplan often delivers meaningfully better value.
Option 2: Transfer Amex Points to Avianca LifeMiles and Book United Flights
Avianca LifeMiles is another powerful Star Alliance program that transfers 1:1 from Amex Membership Rewards and allows bookings on United-operated flights. LifeMiles is particularly well-known among frequent travelers for its straightforward award chart and competitive rates on long-haul routes.
Step-by-Step: Transfer Amex Points to LifeMiles
The transfer process mirrors the Aeroplan steps almost exactly. Log in to your Amex Membership Rewards portal, select “Transfer Points to Travel Partners,” and choose “Avianca LifeMiles.” Enter your LifeMiles account number (sign up free at lifemiles.com if needed), specify the number of points to transfer in 1,000-point increments, and confirm. Transfers typically process within 24 hours.
Once miles land in your LifeMiles account, visit the Avianca website, navigate to the “Redeem Miles” section, and search for United-operated flights on your desired route. LifeMiles allows mixed-carrier itineraries, so you can combine United segments with Avianca or other Star Alliance carriers on the same ticket.
When LifeMiles Beats Aeroplan
LifeMiles sometimes offers better rates on specific routes particularly for United business class on transpacific routes, where LifeMiles has historically priced awards at around 63,000–70,000 miles for North America to Asia business class. Always compare both programs before transferring, as rates can differ by 10,000–20,000 miles on the same itinerary. That gap can represent real money: if Amex points are worth approximately 2 cents each, a 15,000-mile difference equals roughly $300 in value.
Option 3: Singapore Airlines KrisFlyer for United Flights
Singapore Airlines KrisFlyer is a less commonly used but still viable option for booking certain United-operated flights through Amex points. KrisFlyer transfers 1:1 from Amex and is a Star Alliance member, but award availability for partner carriers like United tends to be more limited compared to Aeroplan or LifeMiles. Transfers to KrisFlyer can take up to three business days, which means you should not transfer speculatively always confirm award availability first by calling KrisFlyer’s reservations team or using their online search tool before initiating the Amex transfer.
Pro Tips to Maximize Your Amex Points on United Flights
Getting the transfer right is only half the battle. These strategies will help you extract the most value from your Amex points when booking United award flights
Never Transfer Without Confirmed Award Availability
This is the cardinal rule of points transfers. Amex transfers to airline partners are one-way and irreversible. Once your Membership Rewards points become Aeroplan miles, they cannot be transferred back. Always search for award availability in the partner program’s booking tool first, verify that the seat is bookable, and only then initiate the transfer.
Look for Amex Transfer Bonuses
American Express periodically runs transfer bonus promotions where points transfer at a higher ratio for example, 1:1.25 or even 1:1.35 to specific partners. In 2025 and early 2026, Aeroplan received a 30% transfer bonus during a promotional period. Signing up for Amex’s email alerts and monitoring deal forums can help you catch these windows. A 30% bonus effectively turns 70,000 Amex points into 91,000 Aeroplan miles that’s a business class seat you otherwise might not have had enough points for.
Compare Saver vs. Standard Award Space
When searching for United flights through Aeroplan or LifeMiles, always look for “saver-level” or partner standard award availability. United releases a limited number of lower-priced award seats to partner programs. These seats go fast, especially on popular routes like New York to London or Los Angeles to Tokyo. Booking 5–11 months in advance dramatically improves your chances of finding these seats.
Use Stopovers and Open-Jaws Strategically
Aeroplan allows free stopovers on some international award tickets, which means you can see two destinations for the price of one award. For example, a round-trip business class award from the U.S. to Europe on United might allow a stopover in a connecting city at no extra mile cost. This strategy squeezes significantly more travel value from the same number of Amex points.
How Amex Points Compare to Direct United MileagePlus Earning
It’s worth understanding how using Amex points for United flights compares to simply earning MileagePlus miles directly. The table below lays out the key differences.
Amex Points vs. MileagePlus Miles for United Flights (2026)
| Factor | Amex Points via Aeroplan/LifeMiles | United MileagePlus (Direct) |
| Earning flexibility | High Amex cards earn on all purchases | Limited best earn rate on United purchases |
| Award pricing model | Distance-based (predictable) | Dynamic pricing (variable, often higher) |
| Transfer partners | 21+ airline/hotel partners | Fixed to MileagePlus program |
| Typical economy domestic award | 12,500–17,500 miles (Aeroplan) | 10,000–30,000+ miles (dynamic) |
| Business class transatlantic (one-way) | 55,000–75,000 miles (Aeroplan) | 70,000–120,000 miles (dynamic) |
| Miles expiration | Aeroplan: no expiration with activity | 18 months of inactivity |
Which Amex Cards Earn Membership Rewards Points?
Not all American Express cards earn transferable Membership Rewards points only those explicitly marketed as “Membership Rewards” cards do. In 2026, the main Amex cards that earn transferable points include the Amex Platinum Card, Amex Gold Card, Amex Green Card, Amex EveryDay Preferred Card, and the Amex Business Platinum and Business Gold cards. Cash-back Amex products like the Blue Cash series do not earn transferable Membership Rewards and cannot be used for airline transfers. If United flights are a priority, the Amex Platinum remains the top pick in 2026 for its 5x points on flights booked directly with airlines and through Amex Travel.
Frequently Asked Questions
Can I transfer Amex points directly to United MileagePlus?
No. United Airlines MileagePlus is not an American Express Membership Rewards transfer partner as of April 2026. You must use an indirect route most commonly transferring to Air Canada Aeroplan or Avianca LifeMiles and then booking United-operated award flights through those programs.
What is the transfer ratio from Amex to Aeroplan?
The standard transfer ratio is 1:1, meaning 1,000 Amex Membership Rewards points equal 1,000 Air Canada Aeroplan miles. Amex occasionally runs transfer bonus promotions that temporarily increase this ratio to 1:1.25 or higher.
How long does an Amex to Aeroplan transfer take?
Transfers from Amex to Aeroplan typically process within a few hours and are often instant. In rare cases, they may take up to 24 hours. Always allow at least 24 hours before your planned booking window if you’re transferring for a time-sensitive award seat.
Can I reverse an Amex points transfer to Aeroplan or LifeMiles?
No. Transfers from Amex Membership Rewards to any airline partner are permanent and cannot be reversed. This is why it’s critical to confirm award seat availability before initiating any transfer.
Is it worth using Amex points for United flights instead of booking with MileagePlus miles?
Often yes. Because Aeroplan and LifeMiles use distance-based award charts rather than MileagePlus’s dynamic pricing model, you can frequently find better value sometimes saving 20,000–40,000 miles on the same business class seat. The exact value depends on your specific route and travel dates.
Does Amex charge a fee to transfer points to airline partners?
American Express does not charge a cash fee to transfer Membership Rewards points to airline partners. However, some airline programs may charge a nominal administrative fee or taxes when you book an award, particularly on international itineraries.
What’s the minimum transfer amount from Amex to an airline partner?
The minimum transfer is 1,000 Membership Rewards points, and transfers must be made in increments of 1,000 points. You cannot transfer fractional amounts like 500 or 1,500 points.
Can I combine Amex-transferred miles with miles I already have in Aeroplan?
Yes. Once transferred, Amex points become regular Aeroplan miles and are fully combined with any existing miles in your account. You can pool them together to reach the threshold needed for a specific award booking.
Final Verdict and Recommendation
While you cannot transfer Amex Membership Rewards points directly to United Airlines MileagePlus, the indirect route through Air Canada Aeroplan is your best option in 2026 and in many cases, it’s actually superior to booking through MileagePlus directly. Aeroplan’s distance-based award chart frequently offers lower mile requirements than MileagePlus’s dynamic pricing, especially for business and first class on popular international routes. Avianca LifeMiles is your second-best option, occasionally beating Aeroplan on specific transpacific routes.
The golden rule remains: always confirm award seat availability before transferring any points. Once those Amex points move to Aeroplan or LifeMiles, there’s no going back. Use Amex transfer bonuses whenever available to stretch your points further, book as far in advance as possible to secure saver-level award space, and consider using an Amex Platinum or Gold card as your primary spend vehicle to accumulate Membership Rewards points efficiently. With the right strategy, your Amex points are an incredibly flexible tool for flying United even without a direct partnership
