I currently 6 months into my gold level and 1 of my LAX-HKG and 2 of my HKG-LAX Y flights were upgraded to J. All of my HKG-MNL-HKG segments have been upgraded to J as well. On silver, I was upgraded once MNL-HKG.
Needless to say, I'm enjoying being gold at the moment. One other benefit is being able to get a friend/relative into the lounge.
