Trains are also cancelled on the West Main Line between London Euston and Milton Keynes.
Aviation data firm Cirium said 9,212 flights with 1.6 million seats are scheduled to depart from UK airports between Good Friday and Easter Monday – 78% of the total for Easter 2019.
The busiest day will be today, when some 2,430 flights are due to depart.
