Hello, I've got two questions related to an alert I'd like to generate for DFW/BNE flying QF8 on 10/8/2014 using AA miles.

1) If I do an Award/Upgrade search using:
DFW - BNE on 10/8/2014 for AA in Z/U class
I don't see QF8 (or AA7375) listed. Should it appear, or does it not even get listed if it's not available? Other QF flights are listed, just not this one.

2) If I instead use Flight Availability and do the same search I can find AA 7375 which is what I want. It even lists availability:
J7 D7 I7 Y7 W0 B7 H7 K7 L7 M7 V7 S7 N7 Q7 O0
However when I look on AA.com there is no availability at all. Why would that be?

I'm still a little new to using EF so apologies if this is a basic misunderstanding on my part.
