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

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 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 74 knots. These winds are favorable and may get you there a few minutes early.

Landing
