25,000 miles HND to LAX- IFE system was inoperable the entire flight.

We were returning from HKG. Mr. Cellisttoo was upgraded HKG to NRT, however they refused to upgrade myself or Toddler Cellisttoo as "upgrade only for diamond." They had already split the PNR before we checked in grrrr, so I told Mr. to take it. We had nothing to lose at that point. I assume this was an op-up- but I didn't walk back in the plane to see how full it was. One always hopes it is DL trying out the old NW phantom upgrade. At least two other diamonds were also upgraded on this flight- and were also traveling HKG-NRT-HND-LAX.
