COVID19 – W20 – Mise à jour 31 Mars – EUACA Statistics on Slot Cancellation Anticipation

Microsoft Power BI file content :

Nota: The anticipation of cancelations concerns individual slots and not the whole series. In other words, and as an example, for a series covering the whole season that is canceled at the beginning of the season the first date would be canceled with no anticipation and the last date of the season for that series with the whole season anticipation)

The graphic in tab 2 shows the horizon of cancellations per month. Each chart shows (one chart per month) the number of cancellations (y-axis) per anticipation of cancellation (in number of days, x-axis) –

The chart in tab 1 shows the horizon of cancellations per date of operation.

For every date shown on the horizontal axis, it shows the number of slots that were originally scheduled on this date and cancelled:

A – On the date of operation

B – Between 1 and 7 days in advance

C – Between 8 and 14 days in advance

D – Between 15 and 21 days in advance

E – Between 22 and 28 days in advance

F – Between 29 and 59 days in advance

G – More than 60 days in advance

The data are aggregated for the following list of airports. There is one chart for all airports combined (tab 1) and one per airport (starting on tab 3).

CDG – Paris Charles de Gaulle FR

LYS – Lyon FR

NCE – Nice FR

NTE – Nantes FR

ORY – Orly FR

For all these airports, data were aggregated for cancellations requested for flights scheduled since the beginning of Winter 2020 IATA season.

All data were extracted by slot coordinators as of March 31st.


The graph essentially shows that:

– Very late cancellations, less than one week (cat A and B), are now very few in W20 compared to flights scheduled in March, April and May.

– Late cancellations, between one and two weeks (cat C), were requested by airlines mainly for flights scheduled during the first two weeks of November (A national lockdown was annonced on the 28th of October and was scheduled to last a minimum of one month).

– Early cancellations > 4 weeks (cat F) were almost non-existent for flights scheduled in March and April, but now represent the largest volume of all cancellations (90% of slots in February).
