I was matched to KFES after a few hours. However 4 weeks after taking 3 flight with SQ I was not matched to KFEG so contacted Kris Flyer services. Their response was although I'd taken the 3 flights I had credited the miles for one of them to Asiana and therefore it was not an eligible flight. They claim you need to take the flights on SQ metal and use your Kris Flyer number on the booking. I see no reference for this on the infinite journeys site, anyone heard of this requirement?
