In the calendar view, you can touch the date box and it will bring up the available flights and associated mileage. You don’t need to go elsewhere.

There might be (for example) a “Showing 24 of 36 flights” and “show more” at bottom.

Also, some of the lowest awards require long layovers on an outer island w/ a connection on HA. Don’t select United flights only or you won’t get those options.
