So have been checking flights from Atlanta to Sydney through Dallas on Qantas. Unfortunately I can't fly business so I am looking for premium economy but I did not see it offered for the flights I am looking at.

Someone I know who is a flight attendant for American out of Dallas was saying that she thinks the main cabin on the Qantas flights are never full because of weight restrictions on that particular jet.

Does anyone have experience flying to Australia out of Dallas on Qantas and if so what are your thoughts? Would it be better to say fly Virgin Australia through LAX and fly Premium Economy ?
