A word of caution though. This double miles promotion is a special action by AF/KL Indonesia is only valid for tickets booked and issued in Jakarta. Therefore obviously KLM810/809 CGK-AMS-CGK is the prime candidate for this flight. The Air France flights 256/257 SIN-CDG-SIN have only been included because Air France Indonesia routes its passengers to this flight via an interline agreement with SQ for CGK-SIN-CGK. It is only an Air France Indonesia ticket that will give the double miles promotion. Tickets for AF256/257 issued in Singapore or anywhere else are not eligible for the promotion.
