Air France KLM Flying Blue Miles Sale: Only Until December 22, 2025

Air France KLM’s Flying Blue program is back with one of its most popular recurring promotions — a buy-miles event offering either up to an 80% bonus or up to a 45% discount, depending on your personalized offer, available until December 22, 2025.

When paired with the right redemption, this Flying Blue promo can unlock real value — especially this month, as Ottawa is featured in Flying Blue’s December Promo Rewards with discounted flights to Europe.

Here’s how this promotion works, who it’s best for, and how it pairs particularly well with Ottawa-based redemptions right now.

Flying Blue Buy Miles Promo: The Basics

Until December 22, 2025, Flying Blue members can purchase miles with a mystery offer applied after logging in. Each account will receive either a bonus or a discount — not both.

Personally, I received the up to 45% discount offer.

Current Offer Tiers

Discount Offers

• Buy 4,000–10,000 miles → 35% discount
• Buy 12,000–22,000 miles → 40% discount
• Buy 24,000+ miles → 45% discount

Bonus Offers

• Buy 4,000–20,000 miles → 50% bonus
• Buy 22,000–48,000 miles → 60% bonus
• Buy 50,000+ miles → 80% bonus

With the discount applied, the effective cost per Flying Blue mile works out to roughly CAD 2.5–2.75 cents, depending on the tier.

My Take: When Buying Flying Blue Miles Makes Sense

This isn’t a promotion I’d recommend using to stockpile miles “just in case.”

Instead, this is best used as a top-up strategy — when you’re a few thousand miles short of a specific redemption you already plan to book.

Flying Blue miles shine when:

• You’ve found Promo Rewards
• You’re booking in elevated cabins at a good redemption price
• You need a small number of additional miles to complete an itinerary

And conveniently, December’s Promo Rewards line up perfectly with this sale.

December Flying Blue Promo Rewards: Ottawa Steals the Spotlight 🇨🇦

Flying Blue Promo Rewards are one of the easiest ways for Canadians to save miles on Air France and KLM flights. Every month, select routes are discounted by up to 25% off standard award pricing.

For December, one Canadian city gets the full spotlight:

✈️ Ottawa → Europe from 18,750 miles (Economy)

That’s a 25% discount compared to regular pricing.

If you’re based in Ottawa — or willing to position there — this is one of the cheapest ways to reach Europe using points for winter and spring travel.

Bookings are available now, with travel valid until May 31, 2026.

Why Flying Blue Promo Rewards Are So Valuable

One of Flying Blue’s biggest advantages is flexibility.

Unlike many programs, Flying Blue allows you to redeem miles for any available seat on Air France or KLM flights. There’s no separate award inventory to hunt for — if a seat is for sale, you can usually book it with miles.

Promo Reward tickets:

• Can be booked for anyone
• Work on Air France, KLM, and select partners
• Require taxes and carrier surcharges (paid separately)
• Do not earn miles or XP
• Follow Flying Blue fare rules

---

Real-World Availability from Ottawa

Availability this month is particularly strong, making this Promo Reward more than just theoretical value. Here are some examples below:

Ottawa → Paris (CDG)

• Direct Air France flights
• Strong availability from February through May 2026

Ottawa → Amsterdam (AMS)

• One-stop via Paris
• Excellent availability from February through May 2026

Ottawa → London (LHR)

• One-stop via Paris
• Available from January through May 2026

If you’re traveling beyond Paris, Flying Blue’s network makes it easy to connect onward across Europe.

Important Conditions to Keep in Mind

Before booking, make sure you’re aware of the fine print:

• Taxes and carrier surcharges are not covered by miles
• Promo Rewards are capacity-controlled
• La Première awards require Platinum or Ultimate status and are extremely limited
• Infant tickets must be booked via Flying Blue Customer Service
• All bookings follow Flying Blue program terms and fare rules

---

Why This Matters for Canadian Jetsetters

Even though only Ottawa is featured this month, the value is hard to ignore:

• 18,750 miles is among the lowest Europe redemptions from Canada
• Easy connections across Europe
• Flying Blue is a transfer partner of American Express Membership Rewards (1:0.75)
• A great option for travellers willing to position to Ottawa

When paired with the current buy-miles promotion, this can be a very effective way to stretch your points — as long as you’re booking with a clear plan.

Should You Buy Flying Blue Miles Right Now?

Consider it if:

• You’re short a few thousand miles for a specific redemption
• You plan to book Ottawa → Europe using December Promo Rewards
• You have dates and availability already confirmed

Skip it if:

• You’re buying miles without a clear use in mind

Here’s where the promotion really adds value: if you top up your account during this sale, you can reach the exact number of miles needed for December’s Promo Rewards at a discounted rate.

For Ottawa-based travellers looking to hop to Europe this winter or spring, this is a rare chance to combine a cheap redemption with a buy-miles deal, stretching both your money and points further than usual

Even if you’re only a few thousand miles short, the up to 45% discount can make the difference between waiting and booking today.
