I'm new go being at a level where I get GPUs, and had a quick question.
I book a roundtrip from IAD-ICN in W class, and used a GPU to upgrade from SFO-ICN in R class.
Will I not earn miles for that route? I see that R class is for award seats, but technically I bought the ticket in W class, so I assumed that I would earn base miles + premier bonus for that segment.

When using a GPU to go from coach to business, do you have to make the decision between the miles or the business class seat?

Thanks
