We're taking our first vacation to Australia next year and, while I'm researching flight possibilities, I'm starting to think of the issue of jetlag. We did well going to Europe in '07. Flew out of Calgary on a redeye, arrived shortly after noon at Heathrow, stayed up until 8 pm (when we finally couldn't take it anymore) and went to bed. Aside from an odd wide-awake-at-2:30 stage that lasted over an hour, we were up by 9:30 am the next morning and basically fine on BST. How will we do it with Australia? We're unsure about the route, but it will be ex-YVR, SFO or LAX and be to SYD. United's fares are better than Air Canada's by a large margin, but it's a 6 am arrival at SYD. Air Canada arrives more like 11 am. We'll be flying at the back of the bus, alas, and typically we sleep little on the aircraft, despite our efforts. (Maybe we just need more practice.) What's the strategy for these sorts of times and time changes?
