"The
Qantas Boeing 787-9 Perth to London nonstop service is smashing speed records, with some flights beating the schedule by up to an hour.
Monday’s QF10 flight time from London to Perth was just 15 hours 45 minutes — one hour faster than published as the pilots hooked up with a strong jet stream.
The average speed for the journey was 938km/h but just before the descent into Perth, the plane was flying at 1114km/h."
