We flew Melbourne to LA (QF93) and then onto NY (QF11), on the 05/12/2017, my daughter on the same flights 13/12/2017, and both times the flights were late departing Melbourne and late arrival LA, making it a nail biting rush to catch the second leg of the journey.
The flight itself was excellent. Cabin staff are very friendly and professional. The A380, very smooth. The second leg from LA to NY, was in an older 747 (I was so excited), and one could tell it was a later generation aircraft, noisier, but still excellent service from the cabin staff. The First Officer on the second leg, was incredibly informative and professional.
Apart from late departures, Qantas was excellent.
