Your Flight

We analysed more than 5,000 data points along your route from Newark Liberty International Airport, Newark to Luis Munoz Marin International Airport, San Juan.

Your Journey Beta

Your route takes you over the Appalachian Mountains and crossing the North Atlantic Ocean – these areas can sometimes cause light turbulence.

Mostly Smooth

Overall conditions look mostly smooth with occasional light bumps. Nothing to worry about.

Takeoff

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

Winds Aloft

Winds at cruising altitude are about 39 knots. These winds are favorable and may get you there a few minutes early.

Landing

Landing should feel smooth with possible light bumps 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.
