I did. At least I thought I did when I finally got through to HA on the phone. My reservation was complicated by the fact that it was initially booked through Orbitz and HA had repeatedly refused to touch the reservation up until just past the 24 hours prior to departure mark. I told the agent that I had been trying for 2 days to talk to someone at Orbitz, but could not. I guess I will find out if it was actually canceled when I am ready to rebook, which probable won't be for a while.

Thanks. This morning, I got an email from HA suggesting that if I wanted to just cancel (without immediate rebooking), to click a link. The link went to this form, which is available on the website:
