Air France and KLM have just dropped their latest Flying Blue Promo Rewards for September 2025, and the list this month brings several exciting opportunities for travelers looking to maximize their miles.

These rotating monthly deals offer discounted award tickets on select routes, often slashing the number of miles needed by up to 50 percent. From Economy Class to Business Class, Flying Blue Promo Rewards give travelers a smart way to unlock serious value and book international flights for far fewer miles than usual.

For travelers with flexibility and a stash of Flying Blue miles – or transferable points from programs like American Express Membership Rewards or Chase Ultimate Rewards – these promotions are one of the best ways to stretch your balance and fly farther for less.

Each month brings a fresh list of destinations and discounts, so staying on top of these offers is key to finding hidden gems. 

In this post, we will break down the best deals for September, highlight sweet spots to consider, and show you how to book with confidence.

What Are Flying Blue Promo Rewards

Flying Blue Promo Rewards are monthly award deals offered by Air France and KLM that provide 25 to 50 percent off the usual miles required for select routes. These discounts apply to flights operated by Air France, KLM, and sometimes other carriers in the Flying Blue award program.

The new offers are typically announced on the first business day of each month, but the discounted award space often becomes available one day later. It is always smart to double-check availability before locking in your travel plans.

Most Promo Rewards focus on Economy Class, but it is not uncommon to see Premium Economy or even Business Class deals pop up – especially on long-haul routes. 

Destinations rotate monthly and can include cities across Europe, North America, Asia, Africa, and beyond. Because the list of eligible routes and discounts changes each month, staying flexible and booking quickly can help you grab the best deals before award space disappears.

Here are the booking guidelines for September 2025:

• Valid for bookings made between September 1st, 2025 and September 30th, 2025.
• Valid on flights operating between September 1st, 2025 and February 28th, 2026.
• Discount only applies to the Saver Award rate.
• 25% discount for children ages 2 – 11 is in addition to the Promo Rewards.

The Best Transferable Points Credit Cards

Using a credit card that earns transferable points is one of the best ways to accumulate Flying Blue miles quickly. Since Air France-KLM Flying Blue is a transfer partner of multiple major credit card rewards programs, you can earn flexible points and convert them into miles when needed.

Final Thoughts

Flying Blue Promo Rewards remain one of the best promotions for booking international travel at a discount. 

The September 2025 offers include a mix of destinations across North America, Europe, Asia, Africa, and the Caribbean – with savings of up to 50 percent on select routes.

If you have flexible travel dates and a stash of transferable points, this is a great time to turn those points into real trips. You can transfer miles from American Express Membership Rewards, Bilt Rewards, Capital One Miles, Chase Ultimate Rewards, Citi ThankYou Points, or Wells Fargo Rewards to unlock these limited-time deals.

Promo Rewards can sell out fast, so check availability early and book as soon as you see something that fits your plans. These deals update monthly, so even if you do not find the perfect option now, a great opportunity could be just around the corner.
