Best Ways To Redeem Flying Blue Miles
Flying Blue is the frequent flyer program of two major airlines: Air France and KLM. Naturally, you can use Flying Blue miles to book awards on either carrier. Plus, you can book awards on several SkyTeam partner airlines as well as several non-alliance partners. Better yet, Flying Blue has several sweet spots that are made 20% sweeter because of this transfer bonus. Some of our favorite examples include:
- Short-haul Delta flights (think Washington D.C. to New York-Kennedy) for 5,000 Flying Blue miles (~4,200 Amex points).

Flying Blue Miles Expiration Policy
Flying Blue miles will expire if you don't have qualifying activity in the past 24 months. Unfortunately, transferring your Amex points to Flying Blue doesn't count as qualifying activity. You'll need to take a flight with Air France, KLM, or one of Flying Blue's SkyTeam partners if you are looking for a way to extend your mileage expiration. Or, you can extend the validity of your miles by spending on a Flying Blue co-branded credit card, like the Air France KLM World Elite Mastercard®.
Because of these policies, be extra careful that you don't transfer Amex points to Flying Blue if you won't be able to use these miles over the next two years.
