AI-powered flight briefing
15,500 data points analyzed · HIGH confidence
Your Flight

We analysed more than 15,500 data points along your route from Schiphol, Amsterdam to George Bush Intercontinental Houston Airport, Houston.

Your Journey Beta

9 hours, 9 hours 15 minutes, and 9 hours 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 Atlantic Ocean and over the Appalachian Mountains – these areas 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 45 knots. These winds may delay arrival by up to 33 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.
