Now I am in doubt to fly a DL coded AF operated flight, vs. a DL coded DL operated flight. I know that for the latter I am (close to) top ranked for OP-UPs, but was wondering how this works for an AF operated flight?

Where does AF list a Delta Diamond for operational upgrades?
Same question for KL?

Thanks!
