DH and I are arguing about the best way to get ourselves into Australia time when we fly there in January. We fly from Heathrow at 9.20am and land in Abu Dhabi 8 hours later. We are there for 2 hours then get on another flight for 14 hours to Sydney, landing in Sydney at 7.30pm local time. Accounting for the fact that we will be up at 5am in the UK to get to the airport in time and will not get to our hotel until about 9pm Sydney time (the next day) I think it is best to get up at 5 then stay awake until about 3 hours into the flight from Abu Dhabi to Sydney, have a 3 hour nap then and go to bed as soon as we get to the hotel in Sydney. DH thinks we should stay up the night before, sleep on the flight to Abu Dhabi and then we are on Australai time and can go to bed when we get there.
What is the best option here considering I really struggle to sleep on planes?
