My son and I have made the trip between Australia and the US several times. We've gone Qantas each time and have used the bassinet. The weight limit for the Qantas bassinet is 26lbs. The bassinet was great when my son was smaller but on the last trip his feet and head were touching the sides (he was 7 mos old). He also wanted to sit up and look around so I had to take off the "seat belt" that covers the top of the bassinet when he wasn't sleeping. I'm considering using a car set on our next trip.
