So for long haul on Virgin Australia International, how do the fare codes match up with the economy categories: V Promo, V Deal, V Saver, and V Flexi? I assume that the Premium Deal category is for premium economy class, but how do I figure out whether or not I earn 100% DL SM or 50% on VA flights?

Delta's website says economy classes Y, B, H, K, L earn 100% miles flown but Economy classes E, N, V, Q, T, U, G only earn 50%.
And VA website says that Full Fare Economy is coded Y or B but Discount economy is coded: T, Q, V, N, E, G, K, H, U, L

But for the consumer, their flights are listed as the VPromo/Deal/Saver/Flexi; nowhere (that I can find) explains how Full Fare Economy and Discount Economy are related to V Promo, V Deal, V Saver and V Flexi!!! So how on earth do you figure out whether you earn 50% or 100% DL SM???

Confused!
