Hawaii-based Airlines - HA Fees for Changes on FF Ticket

I have a trip booked SAN-LIH next month on Hawaiian booked with Frequent Flyer Tickets. I may need to change my travel dates to later in the year. Assuming the flights are avaialable at the same mileage levels what is Hawaiian's fee for changing flights?

I have tried calling, but have been on hold for extended periods of time so have never gotten thru.

When I last checked with HA on this in April 2010 (after being on hold for quite a while and going through a few agents) it was $150. I'm not sure if it was per ticket/person or per "batched" reservation (it worked out that we were able to use the original HA Miles booking).

We had to cancel a points booking at Christmastime and think it was $150 to redeposit the points back to my account. Luckily for us we had used the one account for both tix otherwise I think it was going to be $150 per each FF account.

You can now do flight changes on the Hawaiian website.
Seems to cost $50 per person to change date if FF seats are still available at the same mileage level you booked at.
It looked like it was $50 per person whether I changed 1 way or round trip.
I could also change which island I arrived or departed from for the same $50.
