Flying west is so easy on the body.
Our secret is to plan our long haul flights.
Our regular commutes to the UK and Europe at least 24 flying time, takes planning to avoid jet lag.
We fly from Sydney fairly early in the morning our current fav flight is a 8am to Singpore.
8 hours lets us into Singers just after 2 pm local time, 4 pm
Body clock time. no sleeping on the plane
We enter Singers , go for a walk, either High Tea at Raffles or a hawker stall for dinner.
An early nights of at least 8 hours , often 10-12 hrs.
Up at 7 body clock time, 5am Singers time,
The 9am to London.
12 hours later it's 9pm Singers time, but coming up to 4pm in London, again no sleeping on the plane.
Out for dinner in bed by 11pm London time, up on UK time the next morning well rested.
coming back going east we take a late afternoon or evening flight out of Europe, try very hard not to sleep, into Singers later afternoon, head to an airside hotel room, booked for 2 x 6 hr slots, sleep 10-11 hours.
Get up shower have breakfast in the lounge, board a flight at 7am , 9 am Sydney time, 8 hours daytime flying into Sudney around 7pm, head home, sleep 7-8 hours ready to go normal body clock the next day.
It's all in the planning.
