Please provide departure and destination airports. EF needs this, and it saves the person doing the search for you from also having to do the extra legwork.
Anyway, I think an upgrade is unlikely from MEL:
F1 A0 J2 C2 D0 I0 W5 R0 T0 Y9 B9 H9 K9 M9 L9 V9 S9 G0
QF11 (SYD-LAX) looks a better option:
F8 A8 J9 C9 D0 I0 W3 R0 T0 Y9 B9 H9 K9 M9 L9 V9 S9 G0
