i'm trying to find award availability on ly. i see that by looking under avail. with appol or sabre it shows all the available classes and they're supposed to be p,x and j for first/business/economy awards. but for some reason "j" never shows up at all on flights from ewr or jfk, only on flights out of yyz i'm seeing j listed. what am i missing here? how can i check for econ. award availability?
