According to Eurocontrol, more than 800 aircraft have re-entered into service since May.
As of June, there have been only 3,400 inactive aircraft for more than seven days. This number was 7168 when the pandemic crisis made a peak in April 2020.
Eurocontrol notes that it was common for around 2,000 aircraft to be parked at the airports each week before the pandemic. If an aircraft is parked for more than seven days, it is considered inactive by the European aviation body from the moment it landed until its next flight.
