AI-powered flight briefing
15,000 data points analyzed · HIGH confidence
Your Flight

We analysed more than 15,000 data points along your route from London Heathrow Airport, London to Seattle–Tacoma International Airport, Seattle.

Your Journey Beta

16 minutes and 4 hours 35 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 over the Scottish Highlands, crossing the North Atlantic Ocean, and over the Rocky Mountains – 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 a bit bumpy initially, with calm conditions around the airport.

Winds Aloft

Winds at cruising altitude are about 41 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.
