UPDATE: This offer has expired.
I realize I am a bit late to the game for this promotion, but I want to bring it to your attention just the same, as the Air France/KLM Flying Blue loyalty program has become more valuable of late.
Receive a 35% bonus when you transfer Membership Rewards® points to Flying Blue through September 16, 2012. Rather than 1,000 Award Miles, for the period of the promotion, you will receive 1,350 Award Miles when you transfer 1,000 Membership Rewards points to your Flying Blue account.
Look for a detailed post tomorrow, where I will lay out for you some great deals that are available now through Flying Blue. My advice remains the same–if you do not have a specific use for the miles, do not transfer them out of American Express. But just to give you a hint–if you are thinking of traveling to India, the Middle East, Israel, or South America, booking through Flying Blue is often equivalent and sometimes better than booking through Delta or Korean Airlines. Stay tuned.
