British Airways has cancelled eight flights from London Heathrow today and the airport is warning of further disruption to services due to the Queen’s funeral.

Flights from the west London airport are being postponed, cancelled or re-routed today between 13:50 and 15:40 to avoid flying over central London as the Queen’s coffin proceeds from Buckingham Palace to Westminster Hall.

This has resulted in BA cancelling eight flights today.

A source close to the airline told Travel Gossip further disruption is likely on Monday, the day of Her Majesty’s funeral.

In a statement, Heathrow Airport said: “Out of respect for the period of mourning following the passing of Her Majesty The Queen, some flights between 13:50–15:40 on Wed 14 Sept will be disrupted to ensure silence during the ceremonial procession.”

It went on to say that further changes were likely on the day of Her Majesty’s funeral. “We will communicate more details in the coming days. We apologise for the disruption caused, as we work to limit the impact on the upcoming events,” it said.

Other London airports are unlikely to be affected by the funeral procession as they can use different flight paths.

Meanwhile, popular aircraft tracking service FlightRadar24 crashed yesterday as six million people attempted to track the late Queen’s last ever flight, as her coffin was taken by military jet from Scotland to London.

FlightRadar24 tweeted: “In the minute after the transponder of C-17 ZZ177 activated an unprecedented six million people attempted to follow the flight. This unfortunately impacted the stability of our platform.” The blip was short-lived, however, and the FlightRadar24 site is now able to track live flights again.
