Thanks for that
QF009. Based on
Sefty's post I should therefore have paid YQ of USD271, not USD380 - so I'm intrigued where the USD109 has gone
FWIW I deliberately chose the AA codeshare for SYD-JFK as I'm doing the platinum challenge (and since I'm also flying PER-SYD on an AA codeshare, I will get the 10,000EQP during the SYD-JFK flight and so get ~20,000 award miles for that flight^)
