unsure of avios earnings
i have read the earning guide on BA website and looked at this thread but still am unsure of earnings.
i am booked on AA flight in "C" class (upgraded business class using systemwide upgrade from cheap economy fare). i see on the earning chart for BA that "C" class earns 100% miles flown. am i understanding this correctly that flying upgraded business class will earn me 100% miles flown rather than the 25% miles flown for the economy fare that i purchased if i use my BA frequent flyer number to credit miles to my account?
