Marriott Bonvoy to Aeroplan 15% Bonus: Convert for a Seat You Can Book (October 2026)

Last updated: October 5, 2026

Aeroplan is paying a 15% bonus on Marriott Bonvoy conversions from October 1, 2026 at 12:00 a.m. EDT through October 31, 2026 at 11:59 p.m. EDT. There is nothing to register. The bonus is Aeroplan’s, so the Marriott transfer screen keeps showing the ordinary conversion. LoyaltyLobby’s October 1 writeup quotes the offer terms, including the worked example: 30,000 Bonvoy points become 10,000 Aeroplan points at the standard 3:1 ratio, plus 1,500 bonus points.

This is a tool for people who already hold Bonvoy points, or who earn them on a Marriott cobrand, and who can already see an Aeroplan award. It is a poor way to manufacture Aeroplan points out of Chase Ultimate Rewards. Chase transfers to Aeroplan at 1:1. Routing those points through Marriott first returns fewer miles, on a slower clock.

Before you move points: Run your spending through the credit card optimizer. A conversion bonus does not fix a wallet that should be earning a different currency. If the trip is a flight you can book with a bank transfer at 1:1, keep the Bonvoy points for a hotel.

The promo, without the fluff

Aeroplan awards the 15%. Marriott still runs the conversion, at Marriott’s usual rules. Confirm the name match and the cutoff before you submit anything on the last evening.

The quoted terms also exclude a list of other hotel programs from this offer: Accor, Best Western, Choice, Coast, Hilton, IHG, Shangri-La, and Wyndham. The worked example is Marriott. A Hilton or IHG balance is not this promotion.

Other live bank transfer bonuses are on the transfer bonuses page. This conversion is a hotel program paying into an airline, which is a different kind of move from those rows.

The Marriott screen will not show 15%

Because Aeroplan pays the bonus after the fact, logging into Marriott and looking for a banner is the wrong test. The screen should show the ordinary 3:1 conversion. A missing 15% on that page is what the offer looks like while it is live.

What should happen:

1. You convert during the window, from the Bonvoy account whose name matches the Aeroplan account.
2. The standard conversion posts under Marriott’s rules, including the 5,000-mile extra when you send 60,000 points.
3. Aeroplan posts the 15% later. The terms allow up to 8–10 weeks after the promotional period ends.

Eight weeks after October 31, 2026 is December 26. Ten weeks is January 9, 2027. A December award that only prices out if the bonus arrives is inside that gap. Book with Aeroplan points you can already see in the account. Let the 15% show up as leftover.

Do not fire a second conversion because the first one “only” showed 3:1. Both will still be one-way, and the bonus on each will still be on Aeroplan’s clock.

The only conversion table you need

The terms’ own example is 15% of the 3:1 base, on an amount too small to trigger Marriott’s 5,000-mile extra:

30,000 Bonvoy → 10,000 Aeroplan + 1,500 = 11,500.

The same arithmetic on the 3,000-point minimum is 1,000 base miles plus 150, which is 1,150. The terms do not print that line. It is the example’s method applied to the minimum they do print.

At 60,000 Bonvoy, two published readings disagree, and the terms do not settle it. The only worked example stops at 30,000.

• Marriott’s ordinary result is 20,000 from the 3:1 ratio, plus 5,000, for 25,000 Aeroplan points. That 5,000 is Marriott’s standing offer, not this promo.
• 15% of the 20,000 base is 3,000. Add the 5,000 and the total is 28,000. That is how One Mile at a Time computed the chunk.
• 15% of the full 25,000 is 3,750. The total is 28,750. Prince of Travel, AwardWallet, LoyaltyLobby, and Upgraded Points report that figure for 2026, and they describe it as a change from last year, when the 15% skipped the 5,000.

Until the points post, count on 28,000. Treat 28,750 as the reported figure, not as a balance you can already book. 28,750 divided by 20,000 is 1.4375, which is the “about 3:1.44” rate in those writeups. 28,000 divided by 20,000 is 1.4, or 3:1.4. The naked 3:1 is 1.0. Marriott’s 5,000 alone, with no Aeroplan bonus, is 25,000 / 20,000 = 1.25.

The 5,000 lands once per 60,000 points. Four chunks fill the 240,000 daily cap. A fifth chunk has to wait for the next day, and that day still has to fall inside October 31 at 11:59 p.m. EDT.

Convert in a 60,000-point chunk when you want Marriott’s 5,000. A 30,000-point conversion earns the 15% in the terms’ example and leaves the 5,000 on the table. Split a 60,000-point plan into two 30,000-point conversions and you are choosing 23,000 Aeroplan points (two times 11,500) over a chunk that is reported at 28,750 and is at least 28,000.

Do not send Chase points through this

Chase Ultimate Rewards transfer to Marriott at 1,000 → 1,700 through October 15, 2026 at 11:59 p.m. ET. We covered that offer in the Chase to Marriott Bonvoy transfer bonus. Chase also transfers to Air Canada Aeroplan at 1:1. The catalog on this site lists Aeroplan as a Chase partner, and the same guides treat it as a default use of a Chase balance.

Put the two paths next to a 60,000-point Bonvoy conversion. Chase moves Ultimate Rewards in 1,000-point steps. 60,000 ÷ 1.7 is about 35,294, so the transfer that covers a 60,000-point chunk is 36,000 Ultimate Rewards, which become 36 × 1,700 = 61,200 Bonvoy. You would convert 60,000 and have 1,200 Bonvoy left.

The 70% route still gives up 7,250 Aeroplan points against a direct transfer on the reported reading (36,000 − 28,750), and 8,000 on the conservative reading. The 1:1 Marriott route, which is the rate again after October 15, gives up more than half the miles. You also pick up two delays: Marriott can take up to seven days to post the 70% into Bonvoy, and Aeroplan can take 8–10 weeks after October 31 to post the 15%.

Amex, Capital One, and Bilt list Air Canada as a transfer partner in the same catalog. Capital One’s comparisons on this site already describe Aeroplan at 1:1, and the Bilt guide describes most Bilt partners as 1:1. Those balances have a direct door. Building Aeroplan points by first parking them in Bonvoy is the long way around.

What the miles are for, if the seat exists

Aeroplan is useful when the award is a partner seat you can see, on a published distance band, with taxes you have already read. Star Alliance partners are the usual reason to hold the miles. Air Canada’s own flights can price differently from the partner bands. Search the itinerary. Read the cash you still pay. Then decide whether any Bonvoy points should move.

This site’s Sapphire Reserve guide uses 60,000 Aeroplan points for one-way partner business between the U.S. and Europe under 4,000 miles, and 75,000 for 4,001–6,000 miles. Air Canada’s June 1, 2026 chart notice raises that longer business band from 70,000 to 75,000. The same notice does not list a business-class change for the shortest North America–Atlantic band. It does raise North America–Pacific business from 75,000 to 85,000 on the 5,001–7,000 mile band, and partner business from 87,500 to 102,500 on the 7,501–11,000 mile band. Those are chart cells, not seats. If the flight is not there, the cell is a number on a page.

Guides on this site describe Aeroplan as a program without fuel surcharges on many Star Alliance partners. Taxes and any partner booking fee still sit on the award. Price that line. A mileage discount that leaves a huge cash co-pay is a different product from the one the chart suggests.

Here is why the posting delay changes the 60,000-point example. Two 60,000-point Bonvoy chunks are 120,000 Bonvoy points.

• Reported total, if the 15% hits the 5,000 as well: 57,500 Aeroplan. That is 2,500 short of a 60,000-point award.
• Conservative total: 56,000.
• What you can plan around before the 15% posts, if Marriott’s 5,000 is in the conversion: 50,000 (two times 25,000).

A 60,000-point seat is not something you book in October off a fresh 120,000-point conversion unless you already hold the gap in Aeroplan. Three full chunks (180,000 Bonvoy) produce 75,000 Aeroplan points before the 15% if each chunk includes the 5,000. That covers a 60,000-point award and leaves miles behind, at a Bonvoy cost you should compare with the hotel those 180,000 points would have bought. The clean version of a yes is smaller: you are already 25,000 Aeroplan points short of a seat you can hold, one 60,000-point Bonvoy conversion covers that gap once the base and Marriott’s 5,000 are visible, and the 15% is leftover you do not need in order to ticket.

Keeping the Bonvoy points is often the better redemption

MaxPoints planning ranges already used on this site put Bonvoy points at about 0.7¢ to 0.75¢ and transferable points at 1.5¢. Aeroplan is a 1:1 partner of those transferable currencies, so 1.5¢ is the estimate to use for an Aeroplan point you could have acquired directly. It is a planning figure, not a rate Aeroplan guarantees. A partner business award can clear it when the cash fare is high. A soft hotel rate can miss the Bonvoy range just as easily. Price the stay and the seat you can actually book.

At those estimates, 60,000 Bonvoy points and the Aeroplan chunk they become are close. The conversion pulls ahead when the flight’s cash price, minus taxes you still pay, beats the hotel cash those same Bonvoy points would save, minus resort or destination fees the award does not wipe out. If the hotel wins that comparison, keep the points.

Marriott still drops the cheapest night on five consecutive award nights. That can be the reason a stay beats the conversion. The Chase to Marriott piece walks through the fee math on that fifth night. Dynamic hotel pricing means last month’s points rate is not a rate you can demand. Read the room that is on the screen.

A Marriott cobrand earns Bonvoy points as Bonvoy points. That is the audience for this promo: the points are already in the program. Whether the cobrand belongs in the wallet is a separate question. Answer it with the calculator, using your spending, not with a conversion that ends on October 31.

When to convert

Move Bonvoy points only when all of these are true:

1. The award is already on the screen. A specific flight, a mileage price, and the taxes beside it. “We usually fly Star Alliance” is not a booking. Partner space disappears while you are still deciding.
2. You can ticket without the 15%. The base conversion, including Marriott’s 5,000 if you sent a 60,000-point chunk, has to cover the award, or you already hold the rest. If the seat only works once the bonus posts, you are waiting as late as January 9, 2027, and the seat does not have to wait with you.
3. The names match. The quoted terms say a mismatch means the conversion will not process. Fix the accounts before you move points, not after.
4. The flight beats the hotel. Compare the cash you avoid on the award with the cash you avoid if those Bonvoy points stay on a stay you can book, using the ranges above as the tie-break when the two redemptions look similar.
5. You convert only what that award needs. Prefer a 60,000-point chunk when the 5,000 is part of the plan. Stay inside the 240,000 daily cap. Stop when the visible Aeroplan balance covers the ticket.

The clean yes: you already hold the Bonvoy points, you are about 25,000 Aeroplan points short of a partner award you can book as soon as the conversion shows up, the names match, and the hotel stay is the worse use of those points. Convert 60,000. Book when the miles are visible. Leave the 15% for whatever you fly later.

When to keep the points

Leave the balance in Bonvoy if any of these are true:

• Nothing is bookable. The expensive version of this promo is converting 240,000 Bonvoy points on October 31 because the month is ending, then searching an empty Aeroplan calendar into January while the bonus is still in transit.
• The points started as Chase, Amex, Capital One, or Bilt points. Those programs list Air Canada. Send them there directly if Aeroplan is the award. The Chase math above is the proof on the richest hotel detour available this month, and it still loses.
• The trip is a Marriott stay. Fifth night free and a cash rate you have already checked can beat 1.5¢ Aeroplan math. A conversion does not undo itself when the hotel you wanted comes back into inventory.
• The award needs the bonus before year-end. The terms allow 8–10 weeks after October 31. Plan the ticket around points you can see.
• The names do not match, or you are under 3,000 points. The quoted terms say the conversion will not process on a name mismatch, and 3,000 is the minimum.

The verdict

Convert Bonvoy points to Aeroplan this month only for an award you can book with points that will actually be in the account. The window is October 1 at 12:00 a.m. EDT through October 31 at 11:59 p.m. EDT. There is no registration. The names have to match. Convert on Marriott’s site or at 1-800-450-4442. The Marriott screen will keep showing 3:1.

Remember which number is which. The terms’ example is 30,000 Bonvoy → 11,500 Aeroplan. At 60,000 Bonvoy, several October 2026 writeups report 28,750, which counts the 15% on Marriott’s 5,000 as well as on the 20,000 base. The terms do not show that line, and One Mile at a Time’s reading is 28,000. Count on 28,000 until the bonus posts. The 15% can take 8–10 weeks after October 31, into January 2027.

Chase points do not belong in this conversion. 36,000 Ultimate Rewards sent straight to Aeroplan are 36,000 miles. The same 36,000 sent through the Marriott 70% bonus and then into this offer come back as about 28,000 to 28,750 Aeroplan points. Amex, Capital One, and Bilt already list a direct Aeroplan path too.

Find the seat. Read the taxes. Compare that cash with the hotel stay the Bonvoy points would still buy. Then convert exactly the points that award requires, and not one chunk more.

Before you earn the next Bonvoy point toward an airline conversion, run your spending through the credit card rewards calculator.

• Window, registration, names, phone, posting, minimum, cap, and the 30,000-point example are from the offer terms as quoted by LoyaltyLobby on October 1, 2026: October 1 at 12:00 a.m. EDT through October 31 at 11:59 p.m. EDT; no registration; names must match or the conversion will not process; convert online or call 1-800-450-4442; bonus Aeroplan points may take up to 8–10 weeks after the promotional period; minimum 3,000 Bonvoy points; up to 240,000 per day; 30,000 Bonvoy at 3:1 = 10,000 Aeroplan + 1,500 bonus. The quoted terms exclude Accor, Best Western, Choice, Coast, Hilton, IHG, Shangri-La, and Wyndham. Aeroplan says the terms can change.
• 3:1 ratio and Marriott’s 5,000-mile extra are from Marriott’s transfer-points-to-miles page: 3:1 for most airlines, including Air Canada Aeroplan; 5,000 bonus miles per 60,000 points, except American AAdvantage, Avianca LifeMiles, and Delta SkyMiles; United receives 10,000 per 60,000; transfer 3,000–240,000 points per day. The member name on the frequent-flyer account has to match the Bonvoy first and last name.
• 28,750 vs 28,000. Prince of Travel, AwardWallet, LoyaltyLobby, and Upgraded Points report 60,000 Bonvoy → 28,750 Aeroplan for this offer (15% applied to the 20,000 base and to Marriott’s 5,000). One Mile at a Time computes 28,000 (15% on the 20,000 only, then the 5,000). The quoted terms illustrate 15% on the 3:1 base at 30,000 points and do not show the 60,000-point case. 28,750 is the reported figure. 28,000 is the figure to plan around until the bonus posts.
• Chase comparison. Chase → Marriott at 1,000:1,700 through October 15, 2026 at 11:59 p.m. ET is the offer covered in MaxPoints’ Chase to Marriott article. Chase → Aeroplan at 1:1 is how that article and this site’s card guides describe the partner. 60,000 ÷ 1.7 ≈ 35,294 Ultimate Rewards, which rounds up to a 36,000-point transfer and 61,200 Bonvoy points.
• Award bands. 60,000 points for partner business under 4,000 miles, and 75,000 for 4,001–6,000 miles, are the figures in MaxPoints’ Sapphire Reserve guide. Air Canada’s June 1, 2026 flight-reward chart notice publishes the 4,001–6,000-mile North America–Atlantic business increase to 75,000, the 5,001–7,000-mile North America–Pacific business increase to 85,000, and the 7,501–11,000-mile partner business increase to 102,500. Chart cells are not availability.
• Valuations. About 0.7¢–0.75¢ per Bonvoy point and 1.5¢ per transferable point are MaxPoints planning estimates already used on this site. They are not a rate Marriott or Aeroplan pays. A specific award can come out higher or lower. Taxes, partner booking fees, and hotel resort or destination fees still come out of your pocket.
• Eight and ten weeks after October 31, 2026 fall on December 26, 2026 and January 9, 2027. That is calendar arithmetic from the posting window in the quoted terms, not a promise that the bonus posts on either date.

Transfers are one-way. Offers can end early. Confirm the conversion on your own Marriott and Aeroplan accounts, and the mileage and taxes on the award, before you move points.
