NH-ticketed flights (purchased this flight through United.com but has NH flight number and operated by ANA) will display the ANA class fare.

Therefore, as the rules say "ANA fare classes are eligible for Global Premier Upgrades: C, D, J, Y, B, E and G," if I am trying to determine if a flight is eligible for a GPU but it is showing a UA flight number, I can't tell if the ANA class fare is one of the eligible classes?
