The offer
Aeroplan is selling points with a bonus of up to 90% from October 14 through October 29, 2026. The offer is targeted, so the tiers you see after logging in to the buy points page may differ, but the most common structure reported by One Mile at a Time and Prince of Travel is 50% on 5,000 to 25,000 points, 75% on 30,000 to 70,000, and 90% on 80,000 or more.
Aeroplan's list price is 3.75 Canadian cents per point, about 2.6 US cents. At the 90% tier that falls to 1.97 Canadian cents, roughly 1.38 US cents. The worked example doing the rounds is 500,000 points plus 450,000 bonus for C$18,750, about US$13,100, which is the per-transaction maximum during the sale; the normal ceiling is 250,000. The annual cap is one million purchased points, and bonus points do not count against either limit. Canadian billing addresses pay sales tax on top, which pushes the effective price toward 2.16 Canadian cents in the highest-tax provinces; US and Australian addresses are not charged. Points.com processes the purchase.
The third sale in five months
Aeroplan has been selling points hard this year. Point Hacks logged bonuses of 100% in February, 90% in March and May, 110% in July, 100% in September and now 90% again. The July sale priced points at about 1.27 US cents and the September one at about 1.88 Canadian cents, so this offer is a little worse than the last two. If the pattern holds, another sale is likely before the end of the year, which argues against buying now unless you need the points this month.
When the math works
Our Aeroplan calculator puts a point at about 1.45 US cents, so 1.38 cents is only a slight discount to value. The purchases that pay are premium cabin awards priced on Aeroplan's distance-based chart, where a business class seat on Air Canada or a Star Alliance partner routinely returns 2 cents a point or more. North America to Europe in business starts at 60,000 points one way on partners, which at the 90% tier costs about US$830 if you bought every point; the cash fare is usually several times that.
Economy awards and Aeroplan's dynamic-priced Air Canada flights rarely clear the bar. Neither does buying points to hold. Aeroplan points do not expire while the account is active, but a sale that recurs every two months is not a reason to stock up at today's price.
How to buy without regret
Find the award first. Aeroplan shows partner space on its own site and lets you hold a booking for a short time while points land, which usually happens within minutes of a purchase. Count the points you need, subtract what you have, and buy the gap, rounding up to the next tier only if it drops the per-point price enough to matter. Then book, and check the taxes and carrier charges on the award before you confirm; Aeroplan passes on fuel surcharges on some partners but not others, as we noted in our piece on partner fees.
The sale ends October 29. If you do not have a specific flight in mind by then, let it go and wait for the next one.
