You’d hope there would be at least one new 789 ready to do long haul when each 744 retires.
indeed and the actual new fleet plans seem to be somewhat up in the air at present
AIUI
SCL goes to double daily 787 (half of those on LA, 3-4 of which are via AKL the rest direct)
JNB will be a daily A380
HND was slated to be a 380 but apparently the airport has said no, haven’t heard any more since
any other dedicated 747 routes?
(sorry a bit OT)
