Your Journey Beta
1 hour 20 minutes and 1 hour 35 minutes into the flight: Some moderate bumps expected.
The crew may adjust altitude or ask you to stay seated during these sections.
The rest of the flight should be smooth.
Your route takes you over the Pyrenees, crossing the North Atlantic Ocean, and over the Appalachian Mountains – these areas can sometimes cause turbulence.
Smooth Flight
We're expecting smooth conditions throughout your flight. You can sit back and relax.
Takeoff
Takeoff should feel a bit bumpy initially, with calm conditions around the airport.
Winds Aloft
Winds at cruising altitude are about 67 knots. These winds may delay arrival by up to 41 minutes.
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.

Tip
Afternoon flights may encounter more turbulence due to thermal activity as the sun heats the ground, creating rising air currents.

Comfort
Single-aisle mainline jets like this offer a comfortable ride. While you may feel turbulence more than on wide-body aircraft, they are engineered to handle it smoothly.
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
