And the rerouting options to/from NAN are bit slim: FJ is the only airline flying longhauls between NAN and airports in the northern hemisphere and given that FJ has just six A330s and about dozen routes where it uses those planes, that means none operates daily. Australian airlines and NZ provide some additional frequency to their hubs, but I guess that is not really helpful if that NRT-HKG-NAN route already sounds too time-consuming.
