Air France-KLM’s Flying Blue is reducing fuel surcharges it charges for economy awards and charges only the long haul fuel surcharge for premium economy, business and first class awards that include connections. You can read more about this on Flying Blue’s website here.
Edit Apr 25: The current and the new award charts are available on my post here.
There is no change in number of miles required for base level economy awards. There is, however, rise of 25% to 33% in number of miles required for premium economy, business and first class awards.
