So I've just booked my USA flights as a solo traveller and have the following

QF93 - 2A - no one else in F
QF11 - 14K - Can choose any seat row 14 or 11 J K or lower deck and in rows 1, 2, 6, 7 or 8
QF12 - 11 K - Can choose 11A B, any row 12, 14 A B or lower deck any row 1, 2 J K, 3 A B or any 5, 6 or 8
QF94 - 4A can have any in the middle of 1A, 5A and all K except 2.

I've never been in Qantas F, never been in J on a 747 and want the best seats.Thanks.

Regards,

Michael
