AI-powered flight briefing
18,500 data points analyzed · HIGH confidence
Your Flight

We analysed more than 18,500 data points along your route from El Prat De Llobregat, Barcelona to San Francisco International Airport, San Francisco.

Your Journey Beta

A brief bumpy patch may occur during cruise. It's nothing to worry about - just keep your seatbelt fastened.

Your route takes you over the Pyrenees, crossing the North Atlantic Ocean, over the Rocky Mountains, and over the Sierra Nevada – 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 42 knots. These winds may delay arrival by up to 42 minutes.

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.
