I was going to accrue on my Krisflyer Gold. It's a flight from SFO-NRT and NRT- SIN on UA flight number but operated by NH. So, looks like it's going to be 50% accrual only. Had I known this, I may not have chosen the flight operated by NH.

I chose the NH operated flights because they were using a 777-300ER (SFO-NRT) and 787 (NRT-SIN). Newer aircraft, better service and more leg room on their 777-300ER.
