Hi,
Just wanted to post a quick update that the mileage rates that I was looking at (which are different than the OP) are back to what they were a couple weeks ago. There are now many options in both directions in late October/early November for 20k ow from JFK-HNL-OGG-HNL-JFK. Not sure what caused all of the "cheap" space to disappear for a couple weeks, but it appears to be back at least in my case.
