In AJV (Cargo) we have layovers in ANC, ORD, BKK and I guess TPE soon. ANC and ORD can be quite long depending on the pattern.. BKK is 24 hours usually, possibly longer on some patterns in the future..
I will be very suprised if the AirJapan boys see the 787 anytime soon, but I could be wrong.. A good first step would be to see it actually fly!!
