Accidental transfer · Marriott to ANA Mileage Club

Accidentally transferred Marriott points to ANA Mileage Club? Here's how to sell the miles

No bank reverses a points transfer, and Marriott is no exception. The Marriott Bonvoy program terms say that once miles have been awarded to the chosen airline program they may not be changed to another airline program or converted back to Bonvoy points, and that cancellations, changes, reissuance and refunds of miles are not allowed. The Marriott Bonvoy points you moved are ANA Mileage Club miles now, and ANA Mileage Club's rules decide what can happen to them.

If you will not fly on them, Points Plug buys ANA Mileage Club miles from 50,000 miles at 1.12¢ to 1.33¢ per mile, depending on the balance, with payment in 24-48 hours: 100,000 miles fetch about $1,190. This page covers what the miles are worth, what ANA Mileage Club lets you do with them instead, and how to sell.

Can a Marriott transfer to ANA Mileage Club be reversed?

The Marriott Bonvoy program terms say that once miles have been awarded to the designated airline frequent flyer program, they may not be changed to another airline program or converted back to Loyalty Program Points, and that once points are ordered to an account, cancellation, changes, reissuance and refunds of miles are not allowed. Marriott's help centre puts it simply: once miles are awarded to an airline program, they cannot be moved to another airline or converted back into Marriott Bonvoy Points.

That covers both mistakes people make with Bonvoy conversions: choosing the wrong airline, and converting more points than an award needed. The 3:1 ratio also means the points cannot be rebuilt cheaply, so the miles are usually worth more sold than the hotel points would have been.

How Marriott transfers work

  • Points convert at 3:1 to most airlines, with 5,000 bonus miles for every 60,000 points moved. United receives 10,000 bonus miles per 60,000 points; American and Delta receive no bonus.
  • Conversions run from 3,000 up to 240,000 points a day, and for most airline partners the first and last name on the airline account must match your Bonvoy name.
  • Marriott's points-to-miles page lists posting times per airline; most take several days, and the miles are not yours to use until they post.

If the points have not posted, or went somewhere you did not expect

  • If the miles have not posted within the time Marriott lists for that airline, contact Marriott Bonvoy member support with the conversion confirmation.
  • Marriott's terms rule out changing the airline or reissuing the miles once they are awarded, so a conversion to the wrong airline stands.

What your ANA Mileage Club miles are worth now

Published valuations put ANA Mileage Club miles at 1.40¢ to 1.40¢ each, about 1.40¢ on average, as of September 23, 2026. The published figure assumes the miles go on flights; what you actually get depends on the award, and the ANA Mileage Club valuation page lists the redemptions behind the range.

For the miles you hold now, Points Plug pays 1.12¢ to 1.33¢ per mile, rising with the balance; 100,000 ANA Mileage Club miles, roughly what 300,000 Marriott points became at 3:1, fetch about $1,190. The quote form on this page shows the exact figure for your balance.

How to sell ANA Mileage Club miles

  1. Get a quote. The form on this page is preset to ANA Mileage Club; enter your balance and the offer and price per mile appear before you give up anything.
  2. Accept the offer. Our team reaches out to confirm the details and explain how the booking will be handled. You keep your account and your login.
  3. The miles are used to book last-minute travel for pre-qualified customers through your account, usually in one or two bookings rather than many small ones.
  4. You are paid through the method you choose, typically within 24-48 hours of the booking.

The minimum is 50,000 miles in one program, and balances of 100,000, 200,000 and 500,000 earn higher rates. You never pay anything: the quote is free and the offer you accept is the amount you receive. Read how it works and the guide to selling airline miles for the detail.

Airline programs' terms restrict selling miles. Our ANA Mileage Club Q&A quotes ANA Mileage Club's own rule, so you can read it before you decide.

Other ways to use the miles

Fly on them

  • ANA business class between Japan and North America at 100,000 miles round trip in Low season or 105,000 in Regular, and half that one way.
  • ANA first class between Japan and North America from 150,000 miles round trip in Low season and 170,000 in Regular.

The ANA Mileage Club award chart shows what the balance books and which redemptions return the most per mile, and the ANA Mileage Club program guide covers the traps.

Share or pool them

Only within a registered family: the AMC Family Account Service, for members living outside Japan, lets two to eight relatives combine miles for an award for a 1,000-mile registration fee. Miles are otherwise not transferable.

Move them to another program

No. ANA says that once Membership Rewards points have been transferred to your ANA Mileage Club account the transaction cannot be reversed, and ANA lists no conversion out to a bank or another airline.

Points Plug can also convert ANA Mileage Club miles into another airline program from 50,000 miles, with the fee built into the rate the quote shows.

Will the miles expire?

ANA miles are valid until the end of the 36th month counting from the month the flight or service was used, and account activity does not extend them. Miles do not expire while a member holds Diamond status, and never expire for Million Milers (1,000,000 lifetime miles on ANA Group flights). Campaign miles (account groups 2 to 4) have their own campaign-specific validity.

ANA miles are valid until the end of the 36th month after the month they are credited, and nothing extends them, so the transferred batch has its own three-year life.

Avoiding the same mistake next time

  • Find the award seat first and confirm it books with ANA Mileage Club at the price you expect. Only then transfer, and only the amount the award needs; the rest keeps its flexibility in Marriott.
  • Read the partner name on the confirmation screen before you confirm. Several partners have similar names (Virgin Atlantic and Virgin Red, the four Avios programs) and a mis-tap lands the points somewhere else for good.
  • Hold Marriott points in Marriott until a trip is certain. There they keep their cash option and their choice of partners, and transfer bonuses of 20 to 40 percent come round several times a year.
  • Keep the confirmation email until the miles post, and check the airline account under the same name before assuming a transfer failed; posting times run from minutes to two weeks depending on the issuer and the airline.
  • Our guide to transferring credit card points to airlines covers ratios, timing and fees for every issuer.
