AI-powered flight briefing
11,000 data points analyzed · HIGH confidence
Your Flight

We analysed more than 11,000 data points along your route from London Heathrow Airport, London to Newark Liberty International Airport, Newark.

Your Journey Beta

1 hour and 6 hours 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.

Mostly Smooth

Overall conditions look mostly smooth with occasional light bumps. Nothing to worry about.

Takeoff

Takeoff should feel smooth with possible light bumps, with calm conditions around the airport.

Winds Aloft

Winds at cruising altitude are about 56 knots. These winds may delay arrival by up to 46 minutes.

Landing

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.
