However, if this was a flight sold as J/PE/Y why is there F/A class in KVS?
sorry should have included "F" cabin but i missed it from the overall idea of referring to Y>J op ups

kaka mentions J->F would probably follow the known protocol, i.e. the elites in J cabin holding revenue J tickets are eligible and the "upgraded" guy into J either from PE or Y will not be considered for J>F.
