Through September 25 Air France KLM Flying Blue is offering a 100% bonus on purchased miles when you buy between 4000 and 75,000.

With this offer you can buy miles for 1.375 Euro cents apiece or about $0.0166.

Key terms:

During the promotional period each Ivory member can receive a maximum bonus of 75,000 Award Miles. Bonus Miles will be awarded on transactions made between 1 September and 25 September 2017, 23:59 CET+1, and will be credited to the recipient’s account when the transaction is complete. Award Miles are sold in units of 2,000 Miles.

Award Miles are sold to you by Points Inc. Award Miles will be deposited into your account within 72 hours of purchase. You have the right to withdraw your purchase within 14 days as provided in the Buy and Gift Award Miles Program Terms and Conditions. To exercise the withdrawal right or to obtain assistance with the Buy and Gift Award Miles Program, please contact the Customer Service Centre.

Since the miles are sold via Points.com the transaction won’t show up as a travel purchase on your credit card so you generally won’t be earning a spending category bonus from your credit card.

Air France KLM’s Flying Blue program should be interesting to U.S. frequent flyers for several reasons.

1. They offer one-way awards
   
2. They are an American Express Membership Rewards, Citi Thank You points, and a Chase Ultimate Rewards transfer partner.
   
3. They have far more award space on their own flights than Delta has access to.
   
4. They have most of their partners available for online booking

Unfortunately their call centers are frustrating, their website can be too (and has been known to show ‘phantom’ award availability, seats that look available but aren’t really here to book). And they add fuel surcharges onto award tickets.

I’m not a speculative buyer of their currency, but there are certainly strategic uses to put their points to. Here are 17 tricks and things to know about Air France KLM Flying Blue.
