Your Journey Beta
Your route takes you over the Appalachian Mountains and crossing the North Atlantic Ocean – these areas can sometimes cause light turbulence.
Smooth Flight
We're expecting smooth conditions throughout your flight. You can sit back and relax.
Takeoff
Takeoff should feel smooth with possible light bumps, with calm conditions around the airport.
Winds Aloft
Winds at cruising altitude are about 59 knots. These winds are favorable and may get you there up to 22 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.

Data sources & our approach
ZeroTurb's Custom Algorithm: Our proprietary
ZeroTurb Index (ZTI) combines three meteorological indices weighted by their
predictive accuracy — giving you transparent, passenger-focused turbulence probability instead
of vague categories.
This forecast integrates data from:
- ECMWF Open Data — Global atmospheric model (wind/temperature at 13 flight levels)
- NOAA Aviation Weather Center — Pilot Reports (PIREPs), SIGMETs/AIRMETs, TAFs
- NOAA Space Weather Prediction Center — Aurora forecasts for polar routes
- AviationStack API — Flight schedules and airline operational data
