Hey guys, sorry I just want to ask if anyone has had any issues with A3 mileage accrual on upgraded *A flights - I purchased a full fare 'E' ticket with SQ and upgraded it with miles to Business Saver "I". Once I did that, my Krisflyer mileage accrual dropped to '0' - probably "I" is automatically not recognised as an accruing fare class.
I wonder if A3 M&B would have any issues recognising that this is an upgraded ticket and give me my miles based my original class of purchase. I understand that full award redemption tickets for Business Savers are also booked in "I" class , no ?
Many thanks !
