According to the aviation analytics firm, departing flights from UK airports are scheduled to reach 78% of Easter 2019 levels, which Cirium says illustrates "strong signs" of recovery.
The findings come as the aviation industry braces for what is tipped to be a busy weekend after airports recently faced major delays due to staff shortages and cancelled flights.
The busiest day is scheduled to be Good Friday (15 April) with 2,430 departures. Flights are up 576% compared to last Easter and 836% on Easter weekend 2020.
The largest airline, by departing UK flights, is set to be easyJet with 1,952 departures, closely followed by British Airways with 1,648 and Ryanair with 1,588.
The route with the most scheduled flights is Heathrow to New York followed by Heathrow to Dublin and Amsterdam.
