HIGH Confidence
Your Journey Beta
21 minutes, 3 hours, and 3 hours 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 Rocky Mountains – conditions there 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 67 knots. These winds are favorable and may get you there up to 22 minutes early.
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.

☀️ Morning Flight
Morning flights typically experience smoother conditions as the atmosphere is more stable and thermal turbulence hasn't yet developed.
Weather conditions can change. Check again before your flight.
Narrow-Body Aircraft (Medium)
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: We've developed a proprietary
ZeroTurb Index (ZTI) algorithm that combines three meteorological indices weighted by their
predictive accuracy. This gives 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
Disclaimer: This forecast is for informational purposes only. Always consult official aviation weather sources and follow ATC guidance.
How accurate are turbulence alerts? Alerts are based on updated forecast models and pilot reports, and can change as departure approaches.
