All-causes delay and cancellations to Air Transport Europe for Q1 2019

The quarterly issue of our all-causes delay and cancellations to Air Transport Europe, formerly known as the CODA Digests, is part of the EUROCONTROL Network Manager’s reporting on network performance.

Airline punctuality improved by 2.1 percentage points in the first quarter of 2019 (Q1 2019), with 80.8% of arrivals punctual compared to 78.7% in Q1 2018. 

Airline operations remained the main cause of primary delay, contributing 2.9 minutes to the average delay per flight. However, this was 0.3 minutes per flight better, with airlines making considerable efforts such as scheduling improvements and using spare aircraft to improve on-time performance during Q1 2019. This also meant that reactionary delay fell by 0.9 minutes.

Reactionary (knock-on) remained the main cause of delay contributing 4.6 minutes to the average delay per flight. However, its proportion fell with a 42% share of the total generated delay minutes.

While their own performance improved, airlines reported that ATFM airport and ATFM en-route delays increased at 0.8 minutes and 0.6 minutes per flight respectively. Reasons driving this were ATC staffing and capacity issues as well as weather.

Put together, these factors resulted in an average all-causes departure delay of 11.0 minutes per flight, down by 1.3 minutes per flight on Q1 2018 when the average delay per flight was 12.3 minutes per flight.
