Is JAL blocking AA award inventory?
 

Searching for AA metal award space CLT-FLL in February, AA and BA websites show six nonstop options on a certain date, with space in both Y and F, while JAL shows only two (both early morning flights)... what gives?

I have seen recently that the JAL online booking sees very different QR availability than AA. In one case it was definitely ghost availability on AA, but mostly it seems to be JAL having less availability. Though I can't say why...
