During Queen Elizabeth II's funeral, one in seven flights are canceled by the British Airways.
In order to ensure quiet skies over the Queen's funeral, British Airways will be canceling 100 flights to and from the airport on Monday.
In order to avoid disrupting a two-minute silence at the end of the funeral, there will be no aircraft movements for 30 minutes from 11.40 am and 12.10 pm.
There will be a suspension of departures between 3.05 pm and 4.45 pm as a ceremonial procession moves down the Long Walk.
The passengers affected will be contacted and offered the chance to rebook their flight with another airline.
Heathrow and airlines are working closely with NATS to minimize the impact on passengers. Changes to flights will be necessary in order to observe these moments on Monday.
Passengers affected by these changes will be contacted by their airlines about their travel plans.
Heathrow's website will be regularly updated with passenger advice and there will be additional colleagues in the terminals.
The roads around the airport are expected to be very busy and passengers are encouraged to use public transport.
Some passengers will be affected by these exceptional circumstances, and we apologize for that.
A spokesman for British Airways said that on the day of Queen Elizabeth II's funeral, they reduced their schedule and re-arranged some flights to make sure the skies were quiet.
Four US flights to and from the US have been canceled by Virgin Atlantic.
