Plan the time-zone side of your trip

Booking a long flight raises the same questions every time: how long is it really, how many hours ahead or behind will you be, how bad will the jet lag be, who flies it nonstop, and when is the best time to go? Most "time zone" pages answer none of that — they show a ticking clock and leave the rest to you.

Each route page here works it out at a glance. Pick a destination from Flight Routes to see the flight time, the exact time-zone shift, which direction the jet lag runs, the airlines on the route, the business-hours overlap for scheduling calls, and the climate window worth aiming for.
