📊 1,000 data points analyzed HIGH Confidence
Your Flight

We analysed more than 1,000 data points along your route from Phoenix Sky Harbor International Airport, Phoenix to Ontario International Airport, Ontario.

Your Journey Beta

Some bumpy patches are scattered throughout the flight. Keep your seatbelt fastened when seated.

Your route takes you across the Sonoran Desert – conditions there 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 a bit bumpy initially, with calm conditions around the airport.

Winds Aloft

Winds at cruising altitude are about 51 knots.

Landing

Landing should feel smooth 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.

🌤️ Afternoon Flight

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

Wide-Body Aircraft (Large)

Large, twin-aisle aircraft like this generally provide the smoothest ride through turbulence due to their size, weight, and advanced stabilization systems.
