Hi everyone, just trying to understand some experience from fellow members who have had success on getting complimentary business class upgrade from Flex economy fare for Platinum member. I can see there are business class seats available for purchase for my flight and was told by CS that it's not available for my upgrade. The only available upgrade for me is a flight 12 hours later. Am I not doing something right here or is this just the way the complimentary business upgrade benefits work? If so, this is a very poor benefit for Plat member as the system will allocate their availability based on their own algorithm instead of what's really available for sale?
