I'm currently looking at tickets for a trip to Japan in February. (I know that can't be booked that far out yet, I was just checking the shedule for November to see what works for me).
Something like ZRH-CPH-HND-CTS KIX-HND-CPH-ZRH.
While the normal ZRH-CPH-HND works fine on nearly all dates I noticed that the NH operated feeders all book themselves in to Economy, despite the ticket being in Business Class. Now if I remember correctly that might be because domestic Business class is declared as First on NH. Is there a way to force the booking to put these segments in to Domestic First on NH without a huge reprice?
