I'll be flying JL 710 later this month, and when I booked (part of a DPS-ORD fare),
http://www.jal.co.jp/en/inflight/inter/first/f_seat/ showed JL 710 as offering the new Skysleeper Solo seats, but I looked at the page today and SIN-NRT is no longer mentioned.
Any insider information on my chances of the new F seats appearing, or is the web page change reflective of reality?
Generally, there's really no consistency with what First Class seat they will offer on the flight. Usually, they will fly the SkySleeper Dual seat. What is your departure date?
