First of all, I think you have to define what you mean by "availablity."

Current availablity?

Maybe United has awarded a much higher percent of seats to Hawaii, but just because they have already been snagged and American still might have some, would not indicate anything valuable as far as overall statistics.

I don't think you can shop the current markets for any statistical indication of avaliblity (except maybe current availablity at a fixed point in time), and just what those numbers might mean.

Today's current stats could be invalidated the very next day by a revenue management adjustment in either direction (adding or subtracting inventory).

So, IMHO, I don't think any info we could gleen out of the airline's systems today, would mean a darn thing.

And BTW, most airlines have Standard Awards that are available on any flight that has seats available for sale. But I assume you are talking about the lower point requirement Capacity Controlled/Sale/Off-Peak or whatever a particular airline calls it's low point requirement awards?
