Why the LA to Sydney flight is rough

Fifteen hours. Eighteen time zones. A whole day lost to the dateline.

Takeoff is 10pm Los Angeles, Tuesday. Land 7am Sydney, Thursday morning. You crossed the international dateline; Wednesday simply didn’t exist for you. Your body has been awake through what felt like Tuesday night but it’s now Thursday in Sydney. Most travelers arrive zombied for two days.

What Steadway does for your LAX to SYD

The sleep block aligns to Sydney’s night, roughly hours four through twelve of the flight. Wake into Sydney morning before landing. The path covers all of it, drawn from traveler craft and peer-reviewed sleep and circadian research.

One step from the path

Eat the meal. It’s Sydney dinnertime.

On the LA to Sydney flight, the first cabin meal arrives around takeoff hour two. That’s Sydney’s evening, around 6pm. Eat it. Eat it as if it were dinner at home in Sydney, because that’s what it is on the clock that matters. Then settle for sleep around hour four. Wake roughly an hour and a half before landing as Sydney’s morning arrives.
