Definitely agree on the plane size. I did ATL-HNL on an international Delta A330 in First (OR Delta ONe, as they call it) ... three and a half movies, two meals, and an hour nap.
Part of my anxiety is that I'm seeing a medical school classmate and her husband. He has stage 4 duodenal cancer, and probably won't make it through the year. I haven't seen them since 2002, when his father died.
