JetLagPlan: Beat Jet Lag

Long flights leave your body clock in the wrong time zone. JetLagPlan turns your trip into a clear, day by day plan so you know exactly what to do with light, sleep, caffeine, and melatonin to help your body clock catch up.

Tell it where you are flying and when. JetLagPlan reads the time change, works out which way your clock needs to move, and builds a personal schedule for the days before you leave and the days after you land.

Three travel tools make the plan easier to use before departure. Red Eye Fit measures how much of the flight overlaps your usual sleep window without promising that you will sleep. First Destination Day brings local light, caffeine, bedtime, wake time, and optional melatonin timing together. Trip Brief privately shares the route and first day plan through the destination you choose.

A Note on Health

JetLagPlan is informational only and is not medical advice.

Talk to a health professional before using melatonin, or if you take medication or have a health condition.
