Hey there,

You can only list for Y class, and then provided you have an upgardeable ticket, this is usually done either at the time of check in or at boarding. Best ask at the gate. QF don't usually have a brilliant reputation for upgrading interliners without appropriate tickets.. though miracles have been know to happen :-) As for the loads, yes 8 Sept looks very good, just now looking at the factor.

Dress code as follows:

First and Business Class Travel

Suit, trousers (including cords, dress jeans - not blue denim) Business shirts and smart collared casual shirts may be worn open necked. Ties, jackets, jumpers are optional.
