How to qualify for the free Qantas Lounge Passes from Amex Ultimate Card?

To obtain the 2 Qantas lounge passes you have to spend on eligible Qantas flights. If I book QF flights through Amex travel and they cost more than the $450 annual flight credit so I pay the excess on my Amex card does that spend unlock the lounge passes? The T&C’s state that Qantas spend through some travel agents qualifies. Has anyone had experience with this yet? Thanks

Booking via the Amex Travel website does not qualify for the Qantas Lounge passes. You will have to book directly via the Qantas website. I put through a booking via Amex travel and did not receive the passes.
