Cabin Upgrade

Hi just wanted to seek some clarifcation around cabin upgrades. Recently upgraded from ec to UC for 40k miles for two passengers return to DXB however now checking cabin upgrade table for future flights its states single leg journey 20k each way so would that mean it would be 80k miles? thanks

That's correct for Dubai

so has the amount of miles need to upgrade from ec to uc increased of late then?thanks

Not that I know of but I may be wrong ,are you saying in your original post that you upgraded 2 people from Eco to upper return to Dubai for 40,000 miles ? Are you sure it wasn't from PE to upper ?
