Air France-KLM Flying Blue selling miles with up to 80% bonus

Air France-KLM Flying Blue has launched a new flash sale, which offers up to an 80% bonus on miles purchases made by 17 September 2026.

This reduces the cost per mile to 1.69 US cents (2.15 cents), and is one of the largest bonuses in recent memory. However, it’s worth highlighting that you could buy Flying Blue miles for less with Citi PayAll, depending on which card you have.

While it’s less of a household name in Singapore than KrisFlyer or Asia Miles, Flying Blue can offer some good value redemptions. But before you buy miles, you should know that Flying Blue will be devaluing Air France and KLM award tickets on 8 September 2026, by introducing Light fare redemptions with no lounge access or refunds. 

Buy Flying Blue miles with 80% bonus

Flying Blue Sale

From now till 17 September 2026, 5.59 a.m SGT, Air France-KLM Flying Blue is offering up to an 80% bonus on miles purchases.

Offers are targeted, and you’ll need to log in to your account to see how yours is structured. Here’s what I see on mine:

• 4,000 to 10,000 miles: 50% bonus (2.03 US¢/mile)
• 12,000 to 22,000 miles: 60% bonus (1.91 US¢/mile)
• 24,000+ miles: 80% bonus (1.69 US¢/mile)

This is the same structure as the previous sale in July, and you can trigger the highest bonus tier with a minimum purchase of just 24,000 miles.

Non-elite members (i.e. Explorer) can purchase a maximum of 100,000 miles per calendar year, pre-bonus, so during this sale they can receive a maximum of 180,000 miles total.

Elite members can purchase an unlimited number of miles, though there are still limits on how many bonus miles can be earned during a given promotion. For this promotion, it’s 240,000 bonus miles.

What can you do with Flying Blue miles?

The most important thing to know about Flying Blue is that they do not have published award charts. This means you need to be extra careful about buying or transferring miles speculatively, because there’s no guarantee that the prices you observe today will be the same a few months down the road.

You can search for awards even with a zero miles balance, so you can verify the space exists before buying miles and booking it.

Travel on Air France and KLM

Air France Business Class awards between Singapore and Europe cost just 85,000 miles each way, which is significantly less than the 108,500 miles that KrisFlyer would charge.

My recommendation is to use Seats.Aero for faster searching. I was able to pull up an entire year’s worth of award space in just seconds, which saves you the pain of doing guess and check. 

Another option from Singapore would be Bali, where a one-way Business Class award starts from 25,000 miles with KLM (or 21,500 miles with Garuda).

Also be on the lookout for the monthly Flying Blue promo rewards, which consist of discounted awards for travel over the next six months to and from Amsterdam and Paris.

Travel on partner airlines

Air France and KLM are part of the SkyTeam alliance, although they also have non-SkyTeam partners such as Malaysia Airlines and Qantas.

Award prices here are fixed, although again there’s no award chart to refer to; you’ll have to run searches and see what comes up.

Some suggestions include:

• China Airlines
  • Singapore – Taipei (Economy): 14,500 miles
  • Singapore – Taipei (Business): 28,500 miles
• Korean Air
  • Singapore – Seoul (Economy): 17,500 miles
  • Singapore – Seoul (Business): 44,000 miles

Flying Blue devaluation

Before you buy miles, here’s a heads up that on 8 September 2026, Flying Blue will be carrying out a de facto devaluation by introducing new Light fare redemptions with fewer benefits.

In other words, the current redemption levels will become Light tickets with fewer benefits than today. You pay the same, but you get less.

Here’s what it looks like in Business Class, for example.

The biggest losses here are lounge access and the lack of flexibility. Light redemptions are strictly non-changeable and non-refundable. That’s really bad, if you ask me.

For what it’s worth, these changes only affect redemptions on Air France and KLM. The new system does not apply to other redemption partners, where you’ll enjoy the same benefits as you currently do. 

What else should you know about Flying Blue?

• Flying Blue awards can be changed or cancelled for a EUR 70 fee
• Fuel surcharges are not absorbed by the programme
• Flying Blue miles expire after 24 months of inactivity

With regards to expiry, performing selected accrual or redemption activities (such as crediting a flight to the programme or making a purchase with a co-brand card) will extend the entire balance for a further 24 months.

That said, because of the unpublished prices of Flying Blue awards, you should not be holding on to miles for so long that expiry becomes a concern.

What credit card should I use to buy Flying Blue miles?

Flying Blue does not process miles purchases directly, so they won’t code as airline spend. Instead, miles purchases are processed through Points.com in USD under MCC 7399 (Business Services Not Elsewhere Classified).

Conclusion

Flying Blue Sale

From now till 17 September 2026, Flying Blue is selling miles with up to an 80% bonus, which reduces the cost per mile to 1.69 US cents (2.15 cents). 

However, it’s cheaper to buy Flying Blue miles through Citi PayAll, assuming you have a Citi ULTIMA or Citi Prestige Card (and arguably even for the Citi PremierMiles Card).

Since Flying Blue pricing can change without notice, you should never buy miles speculatively. Only buy them if you already have a trip in mind, and have confirmed that award space is available.
