AI-powered flight briefing
3,500 data points analyzed · HIGH confidence
Your Flight

We analysed more than 3,500 data points along your route from London Heathrow Airport, London to Keflavik International Airport, Reykjavík.

Your Journey Beta

2 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 over the Scottish Highlands and crossing the North Atlantic Ocean – 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 76 knots. These winds are favorable and may get you there a few minutes early.
