Flying Blue Promo Rewards: check the calendar before you transfer

Air France-KLM's Flying Blue publishes a rotating list of discounted 'Promo Rewards' routes every month, sometimes cutting the miles price by half versus the standard chart.

Because the list changes monthly and by cabin, it's worth checking the calendar view for your route before transferring points in from a bank program.

Business class Promo Rewards routes are the best value on the list; economy discounts are usually smaller in absolute terms.
