The data will then be shared with the Civil Aviation Safety Authority "To inform the regulatory requirements associated with ultra-long haul flights", said Qantas airline in a press release. "For customers, the key will be to minimize jet lag and create an environment conducive to a relaxing and enjoyable flight. For crew members, it's about using scientific research to determine the best opportunities to promote alertness when on duty and to maximize their rest during down-times on those flights. "Qantas added.

According to Bjorn Fehrm, an aviation and economic analyst at Leeham News, future travelers will find this direct flight very attractive because "There is no stopover in Dubai or Singapore, no extra customs clearance and no transfer stress". The next test flight will connect London to Sydney in November, and the last will take place before the end of the year between New York and London. Flights will be marketed following testing by 2023.
