LucyBell,
How do you get teams to Honolulu in time? There is a way, but I doubt that World Race Productions used it. The famous Shinkansen bullet train from Osaka connecting in either Shinagawa or Tokyo and on to Narita could get teams there in time. The 3 flights that arrive Honolulu in time depart Narita in the evening. The total train time Osaka to Narita at minimum is 3.5 to 4 hours, so there would be ample time to get there IF F3 teams were released from a pit stop in Osaka no later than early afternoon December 19. Waiting at Kansai Airport Osaka for flights from there does not fit the available information.
