I've been speculating for months that UA is dragging their feet on removing flights that they KNOW have almost no chance of operating. As soon as the waiver was granted to stop serving the neighbor islands, all flights should have been scrubbed through September 30.

Because many people book Hawaii trips far in advance, UA is likely holding a lot of cash (mine included) and miles, and they're waiting as long as possible before removing the flights from the schedule and issuing refunds.
