This might help someone (or maybe I'm just a travel rookie and should have figured this out sooner): I made my HA airlines reservation through Chase rewards which I believe is a part of Expedia. Since I was getting nowhere going to HA website directly, I went to Chase and there is a cancellation form that is for people with travel from 8-14 days out. There is the usual disclaimer about all your money (points, I assume) may not be refunded but at least this seems to be where to go if you booked through Expedia/Chase and wish to cancel. I'm still weighing options for travel as there seems to be no benefit to applying for a refund with more than 8 days to go.
