Fog cancels 10 flights at Heathrow and London City Airport

Disruption overview

Passengers at London's Heathrow Airport and London City Airport faced 10 canceled flights early on 9 November 2026, with 7 cancellations at Heathrow and 3 at London City. Visibility dropped to 50 meters or less in places, while a yellow weather warning covering London and much of the South East remained in force until 11:00 am. Light winds and low temperatures were making the fog slow to clear, leaving airport operations affected through the morning. Compensation generally isn't owed for cancellations caused by weather outside the airline's control, but if your flight was affected, you still have rights to a refund or rebooking and appropriate care while you wait.

Disruption details

Thick fog caused 10 flight cancellations at Heathrow Airport and London City Airport on Monday, 9 November 2026. Flights had already been canceled by 6:30 am as visibility fell to 50 meters or less in parts of London.

For affected passengers, this meant an uncertain start to the morning and travel plans that needed rearranging. If your flight was canceled, you can still ask your airline about a replacement flight or a refund, even when weather is responsible.

The early-morning cancellations were split between the 2 airports:

• Heathrow Airport had 7 canceled flights.

• London City Airport had 3 canceled flights.

A yellow weather warning covered London and much of the South East until 11:00 am. The Met Office warned of difficult travel conditions throughout the morning, with fog continuing to affect airport operations.

Forecasters described conditions typical of autumn and winter fog: light winds, clear skies, long nights, and low temperatures. Together, these conditions were making the fog slow to lift. It could persist into the following day if temperatures stayed low.

The weather was also affecting journeys beyond the airports. In Kent, a serious fog-related crash on the M20 closed the motorway for nearly 12 hours, adding to transport disruption across the region.

Compensation generally isn't payable for these cancellations because fog and reduced visibility are outside the airline's control. But that doesn't mean you're without support: under UK 261, a cancellation still gives you rights to rebooking or a refund.

Depending on your circumstances and how long you're waiting, your airline may also need to provide meals, refreshments, and accommodation with transportation if an overnight stay becomes necessary. Weather-related disruption doesn't remove the airline's responsibility to provide appropriate care.

If you're affected, follow your airline's instructions about check-in and boarding, and ask what assistance is available. You can also use AirHelp's free flight checker to better understand whether your particular disruption could qualify for compensation.
