I just return from a trip to Honolulu last week. We had AVOD on both the SEA-HNL leg and the HNL-SLC return. I was in C+ for the SEA-HNL leg, and didn't hear any announcements about AVOD for regular Y either way. On the HNL-SLC flight, they did announce that all AVOD entertainment was free for all passengers, but the actual selection was about 1/3 of what I'm used to seeing on other Delta flights.
