1h30 stopover in Sydney, between Brisbane and Los Angeles, and return flights -> 4 flights with Qantas. Overall a good experience, except some turbulences areas on the second flight between Sydney and Los Angeles (but it's not related to Qantas performance!). The service was rather good with an efficient and friendly staff. The only point of disappointment was the lack of good movies available: I read my book instead. I wouldn't hesitate to fly with them again.
