That's some serious cherry picking!

After responding to your previous post on this topic, I was trying to think about ANY routes on which Chinese airlines competed directly with Western airlines.

LHR-PVG was the first that crossed my mind, so that's a decent catch on your part.
SFO-PVG and LAX-PVG are the only two others I could find. In these cases, MU is cheaper than UA 50% of the time.

I don't want to corner you because I like and appreciate your posts, but I believe you're wrong on this particular topic.
