Doubtful!
On the standard configuration (domestic configured wide body aircraft) at Qantas - seat pitch is below 40"
On the standard configuration (767-200 transcon domestic configured wide body aircraft) at American Airlines - seat pitch is over 40"
SeatGuru Seat Map American Airlines Boeing 767-200 (762)
In fact at AA -
762 in business - seat pitch is almost 50" (2-2-2)
762 in first class - seat pitch is over 60" (2-1-2)
You seriously think Qantas transcon is better
From warm nuts served in a bowl to sundaes made to order, beginning to end - premium transcon on AA is leaps and bounds ahead of QF.
