I flew EWR-NRT-BKK and vv recently. Seems like the 1K meal prioritization memo has not filtered down to all FA's as on some flights the FA's bounced around and on others it was front to back. I like to sit in the last row of the C cabin as it is generally quieter, anywho either I was just lucky but I got my first choice each flight. Personally I don't find the food to be that great on long haul anyway, and plane food doesn't always agree with my stomach and doesn't help to counter jet lag, so if the options left are unappealing I will usually just do the appetizer and salad and take an ambien.
One thing I noticed about the pmco flights is that they know how to keep the champagne cold, a secret they might pass onto their UA colleagues
