Recall that just as seat maps are not an infallible indication of load, neither are the availability listings such as J4 and J0. The number there only indicates the number of
tickets which can be sold at that fare level. It usually tracks the number of unsold seats but not always. (Best example is an oversell condition in coach where all seats have been sold but the airline could still show Y9 B9...)
