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.

AI-powered flight briefing
16,500 data points analyzed · HIGH confidence
Your Flight

We analysed more than 16,500 data points along your route from London Heathrow Airport, London to Phoenix Sky Harbor International Airport, Phoenix.

Your Journey Beta

Your route takes you crossing the North Atlantic Ocean, over the Rocky Mountains, and across the Sonoran Desert – 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 smooth with possible light bumps, with calm conditions around the airport.

Winds Aloft

Winds at cruising altitude are about 36 knots. These winds may delay arrival by up to 32 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.
