Jetlag planning for long-haul trips
TimeShift
Long flights leave your body clock hours behind your destination. TimeShift takes your itinerary and lays the whole journey over daylight and dark where you’re landing — your flights, your layovers, and the hours that are actually worth sleeping in the air — so you arrive closer to local time and spend less of the trip recovering.
