Air France-KLM Flying Blue Miles Sale: Up to 45% Discount (September 2025)
Loading article…
Air France-KLM’s Flying Blue program has just launched a new promotion on purchased miles, offering members the opportunity to buy miles with a discount of up to 45%. This represents one of the better offers we’ve seen from Flying Blue in recent months, making it a potentially attractive opportunity for those looking to top up their accounts for premium cabin redemptions.
Let’s analyze whether this promotion offers good value and examine the best ways to use Flying Blue miles for maximum return on your investment.
Current Flying Blue Purchase Promotion Details
Through 11:59 PM CET on Wednesday, September 17, 2025, Flying Blue is offering a tiered discount on purchased miles:
- Buy 4,000-24,000 miles: 20% discount
- Buy 25,000-49,000 miles: 30% discount
- Buy 50,000-100,000 miles: 45% discount
To access this offer, you must log into your Flying Blue account, as promotions can sometimes be targeted. Some accounts may see slightly different discount tiers or bonuses.
Cost Analysis: Is This a Good Deal?
Without any promotions, Flying Blue miles normally cost between 3.05-3.50 cents each (USD), with the rate decreasing as you purchase larger quantities. With the current 45% discount applied to the maximum purchase amount, here’s how the numbers break down:
| Purchase Amount | Normal Cost | Discounted Cost | Cost Per Mile |
|---|---|---|---|
| 100,000 miles | $3,050 | $1,677.50 | 1.68 cents |
| 50,000 miles | $1,625 | $893.75 | 1.79 cents |
| 25,000 miles | $875 | $612.50 | 2.45 cents |
For context, Flying Blue used to regularly offer 100% bonuses on purchased miles (effectively a 50% discount), allowing members to acquire miles for approximately 1.53 cents each. However, these promotions have become increasingly rare, with the current 45% discount representing the best offer we’ve seen in over a year.
Purchase Limits and Restrictions
Flying Blue imposes the following limits on mileage purchases:
- Standard members: Maximum 100,000 miles per calendar year
- Elite members (Silver, Gold, Platinum): Unlimited purchases allowed, though promotional bonuses may be capped
Additionally, your Flying Blue account must be at least 90 days old to be eligible to purchase miles.
Which Credit Card Should You Use?
Flying Blue mileage purchases are processed by points.com rather than directly by the airline. This means these transactions don’t qualify as airfare or travel purchases for the purpose of earning category bonuses on most credit cards.
Given this limitation, your best options are:
- A card you’re working toward meeting a minimum spending requirement on
- A card that offers strong returns on non-bonused spending
Some of the best cards for non-bonused spending include:
- Citi Double Cash® Card (2% cash back)
- Capital One Venture X (2x miles)
- The Blue Business® Plus Credit Card from American Express (2x Membership Rewards points on the first $50,000 spent annually)
- Chase Freedom Unlimited® (1.5% cash back/points)

Is Buying Flying Blue Miles Worth It?
The value proposition depends entirely on how you plan to redeem these miles. Flying Blue uses dynamic pricing for award tickets, though there are still some general patterns in their award rates. Here are some examples of potential redemptions and their approximate value:
Transatlantic Business Class (60,000-70,000 miles one-way)
- Miles needed: 60,000-70,000 miles
- Cost to purchase miles at 1.68¢ each: $1,008-$1,176
- Typical cash price: $2,500-$4,000+
- Potential savings: $1,500-$2,800+
Intra-Europe Business Class (15,000-25,000 miles one-way)
- Miles needed: 15,000-25,000 miles
- Cost to purchase miles at 1.68¢ each: $252-$420
- Typical cash price: $400-$800
- Potential savings: $150-$380
North America to Asia Business Class (85,000-100,000 miles one-way)
- Miles needed: 85,000-100,000 miles
- Cost to purchase miles at 1.68¢ each: $1,428-$1,680
- Typical cash price: $3,000-$5,000+
- Potential savings: $1,500-$3,300+
The key advantage of Flying Blue is that Air France and KLM often make more award seats available to their own members than to partner airline program members. However, it’s worth noting that saver-level business class award availability on transatlantic routes has become more limited in recent months.
Key Benefits of Flying Blue Redemptions
- Free stopovers: Flying Blue now allows one free stopover on award tickets, even on one-way itineraries
- Promo Rewards: Monthly discounted award tickets on select routes (typically 25-50% off)
- Better availability: Preferred access to Air France and KLM award seats compared to partner programs
- Unique partners: Access to awards on non-SkyTeam partners like Etihad Airways and Aircalin
Fuel Surcharges and Fees
Flying Blue does impose carrier-imposed surcharges (often called fuel surcharges) on most award tickets. These typically range from:
- Economy: $100-150 one-way on long-haul routes
- Business: $200-250 one-way on long-haul routes
While these fees aren’t insignificant, they’re considerably lower than what you’d pay for British Airways or Virgin Atlantic awards, and are in line with what many other European carriers charge.
Airline Partners for Redemptions
Flying Blue miles can be redeemed on a wide range of airlines:
- SkyTeam Alliance members: Delta, Korean Air, Aeromexico, China Eastern, China Airlines, Czech Airlines, Garuda Indonesia, ITA Airways, Kenya Airways, MEA, Saudia, TAROM, Vietnam Airlines, XiamenAir
- Non-alliance partners: Aircalin, Air Mauritius, Bangkok Airways, Etihad Airways, GOL, Japan Airlines (select routes), Malaysia Airlines, Qantas (select routes), Singapore Airlines (select routes), TAAG Angola, Transavia
One notable advantage is that Flying Blue allows first class redemptions on select partners including China Eastern and Garuda Indonesia, which can represent exceptional value.
Miles Expiration Policy
Flying Blue miles expire after 24 months of inactivity. Activity that prevents expiration includes:
- Flying on Air France, KLM, or any SkyTeam partner airline
- Earning miles through a Flying Blue co-branded credit card
- Redeeming miles for flights or other rewards
- Having active Flying Blue elite status
Important note: Purchasing miles directly or transferring points from partner programs like American Express Membership Rewards does not extend the expiration date of your existing miles.
Alternative Ways to Earn Flying Blue Miles
Before purchasing miles, consider these alternative methods for acquiring Flying Blue miles, often at lower effective costs:

- Citi ThankYou Points (1:1 ratio)
- Bilt Rewards (1:1 ratio)
- Marriott Bonvoy (3:1 ratio with 5,000 bonus miles when transferring 60,000 points)

Bottom Line: Should You Buy Flying Blue Miles?
At 1.68 cents per mile with the current 45% discount, buying Flying Blue miles can represent good value in specific scenarios:
- When it makes sense to buy: If you need to top up your account for a specific high-value redemption, particularly in business class to/from Europe or Asia
- When you find exceptional availability: If you’ve confirmed award space on a route where cash fares are particularly high
- For Promo Rewards: If you can combine purchased miles with Flying Blue’s monthly Promo Rewards for even greater savings
- For speculative purchases: Given the dynamic pricing model, buying miles speculatively without a specific redemption in mind carries risk
- When transfer bonuses are available: If you have transferable points and there’s currently a transfer bonus promotion to Flying Blue
- For economy redemptions: The value proposition is typically much weaker for economy class awards
As always, the golden rule applies: search for award availability before purchasing miles, and compare the total cost (miles plus taxes/fees) against cash fares before committing.
For frequent travelers to Europe or those seeking to experience Air France’s refined business class or KLM’s solid premium product, this 45% discount offer presents a compelling opportunity to accumulate miles at a rate that can unlock significant value for the right redemptions.
Frequently Asked Questions
How quickly do purchased Flying Blue miles post to my account?

Can I purchase Flying Blue miles for someone else?
No, Flying Blue does not allow you to purchase miles directly for another member’s account. However, once miles are in your account, you can use them to book tickets for anyone.
What’s the best use of Flying Blue miles?
Generally, long-haul business class redemptions offer the best value, particularly on Air France and KLM metal. The sweet spot is often transatlantic business class at 60,000-70,000 miles one-way, especially when cash fares are high.
How far in advance can I book award tickets with Flying Blue?
Flying Blue allows award bookings up to 359 days in advance. For the best availability, especially in premium cabins, booking as far ahead as possible is recommended.
Are there any fees to change or cancel Flying Blue award tickets?
Yes, Flying Blue charges €50 ($55-60) for changes or cancellations to award tickets. Elite members may receive discounted or waived fees depending on their status level.
Can I combine miles from multiple Flying Blue accounts for a redemption?
Flying Blue does not offer a family pooling feature or the ability to combine miles from multiple accounts. Each redemption must come from a single member’s account.
