is zero for some fare types but usually it's non-zero for at least one fare type within a given class). So if you're willing to poke through the JSON data (whether by hand or by automation), this information is still available by dividing two numbers. Or maybe the actual number of available seats is more interesting, though of course consists vary in length.
Of course, I can't speak to reliability. Pricing seems to have gotten more complicated lately and the understanding I had of the simple "bucket" model appears to be incomplete.
