With 49 participants on board, the Boeing 787-9 Dreamliner completed the 16 km journey from New York to Sydney in 19 hours and 16 minutes.
Qantas group CEO Alan Joyce said: "This is a truly significant aviation premiere, and hopefully it will be a preview of a regular service that will accelerate people's journey from one side of the world to the other. "  During the flight, investigations into the health and wellbeing of the passengers were carried out. The tests ranged from monitoring the pilot's brain waves, to melatonin levels and alertness, to training classes for passengers.
Joyce added, "We know that ultra-long haul flights present some additional challenges, but this is true every time the technology has allowed us to fly on, and the research we are doing should give us better strategies to improve Comfort and well-being on the way. "
The next test flight will be from London to Sydney in November, while before the end of the year there will be another flight from New York to Sydney.
Qantas hopes to operate direct flights from London to Sydney three cities on the Australian East Coast ̵
Captain Sean Golding said: "Overall, we are very Satisfied with flight history and great performance Some of the data we need to assess if it will become a regular service. "

How are the passengers monitored?
Researchers at the University of Sydney's Charles Perkins Center, Monash University, and the Australian Government-backed Cooperative Research Center for Safety and Productivity will examine the impact of long-haul flight on participants.
Passengers in the main cabin carried monitors, and experts from the Charles Perkins Center will examine how a number of variables impacted on their "health, well-being, and body clock," including lighting, food and drink, exercise and sleep patterns, and on-board entertainment ,
Participants were advised to keep a daily log ahead of the flight and two weeks later to show how they feel and how they handle jet lag.
Pilots and cabin crew also keep sleeping diaries. In the cockpit cameras were installed to record the vigilance of the pilots.
"People seem to be totally different in terms of jetlag experience – and we need to look into what contributes to jet lag and fatigue when traveling, so we can and try to reduce the impact of long-haul flights," said Professor Stephen Simpson , Academic Director of Charles Perkins Center, University of Sydney, to CNN Travel.
"We still have a long way to go to understand the diversity of influences – including nutrition, hydration, exercise, sleep, and light – that could work together to the maximum benefit."
Monash University scientists will focus on Focus the flight crew and record their melatonin levels before, during and after the flights, as well as examine brainwave data from electroencephalogram devices worn by the pilots.
This information is then forwarded to the Civil Aviation Safety Authority to obtain information on regulatory requirements related to ultra-long haul flights, "Qantas said in a statement.
