Points Capital

Flying Blue’s “Multiply Your Miles” feature normally lets you buy more miles based on what you earned last month. Right now it’s a lot more generous: through November 23, 2026, you can multiply miles you earned anytime from January 1 through October 31, 2026, and the bigger multipliers come with a bonus of up to 50%.

In plain terms, it’s a sale on Flying Blue miles where the size of your purchase is tied to how much you already earned this year.

How the promotion works (as of November 2026)

• Dates: November 3 to November 23, 2026.
• Which miles count: eligible miles credited between January 1 and October 31, 2026. Purchased miles, gifted miles, miles transferred between members and goodwill credits don’t count toward your base.
• Multipliers and bonuses: 2x (no bonus), 4x (15% bonus), 6x (20%), 12x (30%) and 16x (50%).
• Limits: up to 1,000,000 miles during the promo, with a maximum of 500,000 bonus miles.
• One shot: you get one transaction, so pick your multiplier before you pay.
• No status help: multiplied miles are award miles only and don’t count toward Flying Blue elite status.

European outlets that ran the numbers put the regular price at about 1.60 euro cents per mile and the 16x tier at about 1.07 euro cents per mile. Your price may be different, and both reports note that the multipliers, prices and eligible miles can vary by account. What you see when you log in is what counts.

For US members, we don’t have a confirmed dollar price for this round. For reference, in the June 2026 version of this same promo, Prince of Travel’s US-dollar example worked out to about 1.31 cents per mile at 16x and about 1.96 cents at 2x. Treat that as a ballpark, not a quote.

How to check your offer

Log in to your Flying Blue account and look for the Multiply Your Miles option under ways to buy miles. You’ll see your eligible base and the price for each multiplier. Before you pick, do this quick check: take the total miles at your multiplier and divide the price by it. That’s your real cost per mile, and it’s the only number that matters.

Who this is for

This mostly helps people who earned a decent pile of Flying Blue miles this year and are a little short of a specific award. If you only earned a few thousand miles in 2026, your base is small and the bonus won’t move the needle much.

If you’re sitting on Chase Ultimate Rewards points, think about this part first: Chase transfers to Flying Blue, and in the June version of this promo Prince of Travel reported that miles transferred in from bank programs counted toward the base. We’d confirm that in your own account before counting on it, but it means transferring points could both cover part of an award and raise how much you’re allowed to multiply.

Our take

This is a good promo for a narrow group of people, and a trap for everyone else.

Here’s why. The lower tiers barely beat the normal price, so they’re not much of a deal. The real discount sits at 12x and 16x, and those tiers mean a big check. Using the European example, the 16x tier on a modest 4,000-mile base cost €1,024. That’s a lot to spend on miles you don’t have a plan for, especially since Flying Blue prices awards dynamically and can change what an award costs.

We’d buy if you already found the exact award you want, say one of this month’s Promo Rewards, and the math beats paying cash for the ticket. Remember that Air France and KLM awards also come with taxes and fees on top of the miles. We’d skip it if you’re just “stocking up,” or if you can cover the gap by transferring credit card points you already have.

Terms, prices and eligible miles may vary by account and can change. Check your Flying Blue account before buying.
