Your Journey Beta
21 minutes into the flight: Expect more intense turbulence. Keep your seatbelt fastened.
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 directly to your destination.
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 expect some bumps during climb, with calm conditions around the airport.
Winds Aloft
Winds at cruising altitude are about 105 knots.
Landing
Landing should feel expect some bumps on approach 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
