Yup, and there's actually a lot of good info upthread and in the Wiki which helped me put together this trip. I had a pretty limited set of dates when I could do the trip though and even if all other sectors were OK, I could never find the Z fare for HNL-MAJ sector for the dates I wanted. I guess it's a relatively small J cabin given that 4 seats out of 16 are blocked for the crew, and there's a fair number of officials, military, etc. flying.
Also, I needed a one-way as I was staying a few days in Japan at the end of my trip and then continuing HND-LHR (JAL's J product on their 787 was such a refreshing change after multiple segments on UA).
