Based on my search, I see that economy is: YBHKMLV (soon YBHK are only upgradable fare)...
For business, revenue is JCDI. Redemption is U (full, upgrade or companion award)...
First: F, A
Business: J, C, D, I
Economy: Y, B, H, K, M, L, V, S, N, Q, O
Awards (regardless of how it's redeemed, i.e. companion, upgrade, full redemption have the same fare codes)
First: Z
Business: U
Economy: T
But like others have said, I have noticed that even though companion, award and full redemptions come from the same booking class, I have experienced circumstances in which upgrade Z was available but full redemption Z was not.
