Transfer Chase Ultimate Rewards to United MileagePlus

How points transfers work and why they matter

Transferring credit card reward points to an airline or hotel loyalty programme is one of the most powerful moves in travel, unlocking redemptions worth several times more than cash-back. This calculator shows you the exact number of miles or points you receive at the current published ratio before you commit to an irreversible transfer.

What transferable points are and how they differ from programme miles

Most premium travel credit cards earn a flexible rewards currency rather than airline-specific miles. The four major flexible currencies in the United States are Chase Ultimate Rewards, American Express Membership Rewards, Citi ThankYou Rewards, and Capital One Miles. Each of these currencies sits in a central pool and can be moved to a menu of airline and hotel partners at published ratios. Because you can route them to whichever partner offers the most compelling award for your specific trip, they tend to carry higher valuations than miles that are locked inside a single programme's network.

Airline-specific miles, by contrast, are earned directly through flying, co-branded credit card spend, or partner activity and can generally only be redeemed within that airline's own award chart. Hotel loyalty points follow the same model: Marriott Bonvoy points, for example, are typically redeemed within the Bonvoy portfolio, though Bonvoy does allow transfer to a wide range of airline partners at a 3:1 ratio with a 5,000-mile bonus on every 60,000 points. Understanding the distinction between flexible currencies and programme-specific currencies is the first step toward optimising how you earn and spend your rewards.

What transfer partners and transfer ratios mean

A transfer partner is an airline or hotel programme that has a commercial agreement with a credit card issuer allowing cardholders to convert their flexible points into that programme's currency. The transfer ratio describes how many destination programme units you receive for each source point you convert. A ratio of 1:1 means 1,000 Chase Ultimate Rewards points become 1,000 United MileagePlus miles. A ratio of 2:1 means you receive two destination units for every one source point, which is relatively rare and represents a particularly attractive conversion. A ratio of 3:1, which is common for hotel-to-airline transfers, means you surrender three hotel points to receive one airline mile. Whether that exchange makes sense depends entirely on the redemption value of the destination currency relative to what you gave up.

Transfer bonuses are temporary promotional offers where the issuer or the destination programme provides additional miles or points on top of the standard ratio. A 30 percent transfer bonus to Air France/KLM Flying Blue, for example, would turn 10,000 Amex Membership Rewards into 13,000 Flying Blue miles instead of the standard 10,000. These promotions can dramatically improve the economics of a transfer and are worth watching if you are planning a large move. The bonus column in the reference table above notes any promotions currently flagged in the published reference data, but promotions change without notice. Always verify directly on the programme's transfer partner page before initiating.

How to use this calculator

The transfer calculator is designed to take the guesswork out of the arithmetic before you commit to a transfer. Follow these steps to get an accurate output for any route.

1. Select your source programme. Choose the credit card rewards currency or hotel programme you are converting from. The dropdown lists the major transferable currencies: Chase Ultimate Rewards, Amex Membership Rewards, Citi ThankYou Rewards, Capital One Miles, and Marriott Bonvoy.
2. Select your destination programme. Choose the airline or hotel loyalty programme you want to transfer into. The available destinations update automatically based on the transfer partnerships published by the source programme. Only valid transfer routes are shown.
3. Enter the number of points to transfer. Type in the number of source points you plan to convert. The calculator applies the published ratio and displays how many destination miles or points you will receive. If an active bonus is recorded for the route, the bonus amount is shown separately so you can see the gross total.
4. Review the output and verify before transferring. The result is a real-time calculation based on the reference ratios in the table above. Before initiating the actual transfer, always confirm the ratio and any bonus on the programme's own transfer partner page, as promotions and ratios can change between updates.

Worked examples in USD

The following examples illustrate how the transfer math works across the three most commonly used transfer scenarios. All dollar figures are in USD and are illustrative based on published valuation estimates.

Example 1: Chase Ultimate Rewards to United MileagePlus (ratio 1:1)

Suppose you hold 80,000 Chase Ultimate Rewards points and you have found a round-trip business-class saver award on United to Tokyo, priced at 70,000 MileagePlus miles. The 1:1 transfer ratio means you convert 70,000 Chase points into exactly 70,000 United miles, leaving 10,000 points in your flexible balance. That Japan business-class award might retail at $4,200 in cash. At the The Points Guy published valuation of 1.35 cents per United mile, those 70,000 miles carry a baseline value of $945. But the actual redemption value when applied to that $4,200 seat works out to 6.0 cents per mile. The calculator gives you the mile output; you then compare that output against the cash price of the award to determine whether the transfer makes sense. In this case, with a premium-cabin redemption, the math is clearly compelling.

Example 2: Amex Membership Rewards to Air France/KLM Flying Blue (ratio 1:1, with bonus)

American Express periodically runs transfer bonuses to Flying Blue, which has its own monthly Promo Rewards award sale that can make certain routes exceptionally good value. Assume you have 50,000 Amex Membership Rewards and a 30 percent transfer bonus is active. Entering 50,000 points in the calculator with a 30 percent bonus applied produces 65,000 Flying Blue miles. If you use those miles for a business-class award to Europe at 50,000 miles one-way (during a Promo Rewards sale), the remaining 15,000 miles cover a future economy redemption to a short-haul European destination. Without the bonus, you would have had only 50,000 miles, making that two-trip strategy impossible. The transfer bonus is therefore the deciding factor, and the calculator makes the arithmetic transparent before you commit.

Example 3: Marriott Bonvoy to American Airlines AAdvantage (ratio 3:1, plus 5,000 bonus miles)

Marriott Bonvoy's transfer to airline programmes follows the Bonvoy transfer partner terms, which publish a 3:1 ratio and a 5,000-mile bonus on every 60,000 Bonvoy points transferred. If you transfer 60,000 Bonvoy points to American AAdvantage, the calculator outputs 25,000 AAdvantage miles: 20,000 at the 3:1 base ratio plus the 5,000-mile bonus. At the published AAdvantage valuation of around 1.77 cents per mile, those 25,000 miles represent approximately $443 in baseline redemption value. Whether that represents a good exchange for 60,000 Bonvoy points (themselves valued at around 0.84 cents each, or $504 total) depends on whether you can use the AAdvantage miles for a specific high-value redemption. The 3:1 hotel-to-airline transfer is rarely the best use of hotel points unless you are targeting a specific saver award that delivers substantially more than the baseline valuation.

Methodology and important caveats

The transfer ratios in this calculator are sourced from the published transfer partner pages of each issuer. Ratios are point-in-time reference data and may not reflect the latest promotional changes, new partner additions, or ratio adjustments that issuers can implement without notice. The source link in the reference table takes you directly to the programme's own transfer partner page so you can verify current conditions before initiating any transfer.

The single most important caveat for any transfer decision is irreversibility. Transfers from a flexible currency to an airline or hotel programme are almost always one-way and permanent. Once you convert Chase Ultimate Rewards into United miles, those miles cannot be converted back. This is why this calculator exists: to give you the precise output in advance, before you take an action you cannot undo. The advice from every major frequent traveller resource, including The Points Guy, is to transfer only when you have confirmed the award space, know the exact mileage price, and have verified that the cash alternative is materially worse value. Speculative transfers made before confirming award availability carry the risk of locking currency into a programme where you may be unable to find suitable redemptions.

Transfer minimums and increments are another practical consideration. Some programmes require transfers in minimum blocks (for example, in increments of 1,000 points), which means you may not be able to transfer an arbitrary round number. The reference table notes any minimum or increment restrictions where they are published. Always confirm the minimum on the programme's own site before you enter the transfer amount in their portal.

Finally, transfer processing times vary. Most airline transfers from the major flexible currencies complete within minutes to a few hours, but some routes, particularly hotel-to-airline transfers, can take up to three to five business days. If you are booking an award that requires miles to be in the destination account by a specific date, build in sufficient lead time and do not assume the transfer will be instant.

Frequently asked questions

Are points transfers reversible?

In almost all cases, no. Transfers from a flexible currency like Chase Ultimate Rewards or Amex Membership Rewards to an airline or hotel partner are permanent. The destination programme receives the miles, and the source account is debited. There is no reversal mechanism. This is the primary reason to use a calculator before transferring: confirming the output and having a specific award in mind before you initiate the conversion.

How long do transfers take?

Most airline transfers from Chase Ultimate Rewards, Amex Membership Rewards, and Citi ThankYou Rewards complete within a few minutes to a couple of hours. Hotel-to-airline transfers, such as Marriott Bonvoy to AAdvantage, can take up to three to five business days. Capital One transfers generally complete within two business days. If you are booking a time-sensitive award, initiate the transfer several days before you need the miles in the destination account.

Do I need to be a cardholder to use this calculator?

No. This calculator is entirely public and requires no login. It uses published transfer ratios from each programme's transfer partner pages to compute the output. You need to be a cardholder of the relevant credit card and a member of the destination programme to actually initiate a transfer, but you can use this tool to plan and compare routes without any account.

What happens if a transfer bonus is running?

A transfer bonus is a temporary promotional uplift where the card issuer or the destination programme grants additional miles on top of the standard ratio. For example, a 25 percent bonus on a 1:1 route turns 10,000 points into 12,500 miles. The calculator shows the bonus amount separately if one is recorded in the reference data, so you can see both the base output and the bonus total. Because bonuses change without notice, always verify the current bonus directly on the programme's transfer page before transferring.

Which flexible points currency has the most transfer partners?

American Express Membership Rewards and Chase Ultimate Rewards both maintain extensive partner networks. Amex lists over 20 airline and hotel transfer partners; Chase lists more than a dozen. Citi ThankYou Rewards and Capital One Miles each offer a smaller but still competitive set of partners. The right currency for you depends on which partners serve the routes you want to fly, not purely on partner count. A programme with 6 partners is equally valuable if those 6 happen to be exactly the airlines and hotels you use.

Is a 3:1 hotel-to-airline transfer ever worth it?

Rarely as a routine strategy, but occasionally yes. The 5,000-mile bonus that Marriott Bonvoy adds on every 60,000 points transferred improves the effective ratio to roughly 3.3 points per mile. If you can target a high-value saver award where the cash retail price is very high relative to the miles required, the transfer can deliver positive value even after the 3:1 dilution. For most travellers, however, redeeming Bonvoy points directly against hotel stays delivers better value than converting to airline miles at a 3:1 ratio.

Can I split a transfer across multiple destination programmes?

Yes. Most issuers allow you to initiate multiple separate transfers to different partner programmes, each from the same source balance. You could, for example, send 30,000 Chase Ultimate Rewards to United and 20,000 to British Airways in two separate transactions. Each transfer must meet any applicable minimum or increment requirement individually. There is no limit on the number of different partners you transfer to within a given period, though issuers may apply per-transfer maximums or daily limits. Check the terms for your specific card before splitting a large balance across multiple partners.
