Qantas QF107 Sydney to New York Haven't had the opportunity to fly long haul on an A380 yet so to date I find that the 747 is still the best pick for long haul. Flight from Sydney to LA is 13-14 hours and this time we went through the newer, larger and quicker immigration and customs area at LAX.
Last time a couple of years ago this took what seemed like hours. Also last time there was an aircraft change but this time we re boarded the same aircraft and on to NYC, approx 5 hours flight. The LA terminal used now is different and newer than the shared facility Qantas were using with American Airlines for the second leg LA to JFK.
Still electronically finger printed and photographed but avoided the random frisking that passengers are subject to when re boarding domestic flights in the US.
