We know turbulence can feel scary - especially on long flights.
This report is built for you: what bumps feel like, when they happen, and why they don't put the aircraft in danger. Many passengers feel exactly the same way.

Your Journey Beta
1 hour 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 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 a bit bumpy initially, with calm conditions around the airport.
Winds Aloft
Winds at cruising altitude are about 47 knots.
Landing
Landing should feel a bit bumpy on descent 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
