I did a search but was concerned about the changes posted 8/1.
Is it still possible to buy an "A" class ticket on this route on with all QF flight numbers on a ticket issued by QF (081)?

It used to be possible but I want to make sure I can still do it. Advantage customer service is confused.

This is the only excepiont page under Qantas on AA.COM.
