ANA is missing out on some connecting opportunities from JFK without the NRT flight, which was intended to feed into the afternoon connection bank.
MNL-HND arrives at 8pm, can't connect to JFK flight that leaves in the morning.
HND-SGN departs at 5pm, too early for JFK arriving at 6pm (new earlier JFK departure should fix this)
HND-CGK/MNL/SIN all depart at 10am
Other connections can be made same day but with long layovers vs NRT and other hubs.
HND-BKK departs at midnight, 6 hour layover, will be 10 hours with new schedule
CGK/SIN/BKK/SGN-HND arrives before 7am, which means 3.5 hour connection to the JFK flight
HND flights have never been timed for or oriented towards connecting passengers. They're mostly timed to suit local O&D demand.
