AI-Powered Flight Briefing
📊 3,000 data points analyzed HIGH Confidence
Your Flight

We analysed more than 3,000 data points along your route from London Gatwick Airport, London to Arlanda, Stockholm.

Your Journey Beta

48 minutes, 1 hour 20 minutes, and 1 hour 30 minutes 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 crossing the North Sea – 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 smooth, with calm conditions around the airport.

Winds Aloft

Winds at cruising altitude are about 45 knots. These winds are favorable and may get you there a few minutes early.

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.
