If I take off Sat 12noon with the time difference and flight being approx 23 hours from England what will be the day and time when I arrive.and if I leave australia say sat 12 noon what will be the day and time when I arrive back. THANKS
If you leave the UK at noon on Sat, then depending on whereabouts in Oz you are flying to, it will be about 10pm Sat night at take off - therefore a 23 hour flight time will mean you arrive approx 9pm Sun night.
On the way home, if you leave Oz at 12 noon on a Sat, the UK time will be about 2am Sat morning, so a 23 hour flight will mean you arrive back in the UK at 1am on Sun morning.
I think there is only 1 Qantas flight that leaves the UK at lunchtime (certainly was when I was booking a flight earlier this year). No matter which airline you go with (which is basically Qantas, BA or Virgin for a direct flight) you will leave between 9.30pm and 11.30 pm (we left at 10pm), land in Singapore/Hong Kong/ Bangkok (landed Bangkok 3.00pm local) take off a couple of hours later and land at Sydney around 6am-7am (landed 6.15am). From memory the first flight was 11 1/2 hrs, second 8 1/2 hours. You will then walk through Sydney airport like a zombie!!! So in summary, we took off 10pm Thursday and arrived Sydney 6.15am Saturday.
