Search your desired city pairs on the web site (on computer, not mobile device). You can then pick any day of a month and click the calendar option to see the award pricing on your route every day that month. Sometimes you may find something worthwhile. It’s also a good way to look at international partner award availability. 60k one way business class to Japan is one example that people are able to find with some flexibility using the calendar search.

but if you’re thinking of the “good ole days” when there was fixed pricing based on a pie in the sky award chart with sAAver and AAnytime lists, those days are long gone.
