FTers always empathize with any flight changes. You might call HA again and ask to change your reservation to an itinerary that better suits your needs, since they did change your reservations. In addition, you can consider asking for a full refund based on the schedule change. Get your money back and book a flight on another carrier that will listen.

If they still don't allow, just call back and try again.

If, however, you're not successful, pick up a bump on your overbooked flights to spite the airlines

good luck! aloha
