I did it about 10 years back LAX-NAN on the old 744. Got it both directions for about $300 each for two of us. Other pax were not happy that we paid $800 for our tickets and $300 for the upgrades, making our trip $1400 compared to the $4-5k they paid for biz. I've heard minimum bids on the 330 can be as high as $1000-1200 each direction.
