Conclusion

It is difficult to believe that the combined frequent flier program of Air France and KLM, Flying Blue, has turned 20, as I can still vividly remember KLM’s Flying Dutchman. I am not sure if I was ever part of Air France’s one, although I must have.

This is a small award miles bonus for those who book their Air France and KLM flights by June 20^th for travel through December 31.
