Your Flight

We analysed more than 8,000 data points along your route from San Francisco International Airport, San Francisco to John F Kennedy International Airport, New York.

Your Journey Beta

Some bumpy patches are scattered throughout the flight. Keep your seatbelt fastened when seated.

Your route takes you over the Sierra Nevada, over the Rocky Mountains, and over the Appalachian Mountains – these areas can sometimes cause turbulence.

Some Bumps Ahead

There are a couple of short sections with bumps, but nothing out of the ordinary. Turbulence can feel uncomfortable, but it is not dangerous. Aircraft are designed to handle it easily. Pilots often adjust altitude or route to find smoother air.

Takeoff

Takeoff should feel smooth, with calm conditions around the airport.

Winds Aloft

Standard wind conditions expected at cruising altitude.

Landing

Landing should feel smooth with typical approach conditions.

You're in Safe Hands

If you feel nervous at any point, remember that turbulence is expected, safe, and part of normal flying. The crew is monitoring everything, and the aircraft is built to handle far more than anything you will feel. Have a safe and calm flight.
