En-route ATFM delay per flight
Total en-route delay by reported ATFM delay cause
Following the disproportional increase in 2018 and the subsequent major disruptions for passengers, en-route ATFM delays fell by 9.0% in 2019 to reach 17.2 million minutes; the second highest level since 2010.
The average en-route delay decreased from 1.74 to 1.57 minutes per flight in 2019: flights were delayed more frequently, albeit with shorter average delays than in 2018.
According to the ANSPs, ATC Capacity (43.9%) attributed delays remain the main portion of en-route ATFM delays, followed by ATC Staffing (24.3%), Weather attributed delays (21.2%), and ATC 32 disruptions/industrial actions (7.2%).
The observed performance improvement in 2019 was mainly driven by less delays attributed to adverse weather (-24.1% vs 2018) and ATC disruptions/strike (-13.5% vs 2018).

Share of controlled flights delayed by en-route ATFM regulations (%)

The number of flights that were delayed by en-route ATFM regulations increased to 9.9% of all flights (+0.3 percentage points vs. 2018). in 2019, one flight in 20 was subject to an airport ATFM regulation and one in six was subject to an en-route ATFM regulation. 3.7% of all flights were delayed for more than 15 minutes because of en-route ATFM regulations but those flights accounted for 70% of all en-route ATFM delays.

En-route ATFM delay by ANSP


In 2019, average en-route delay per flight was highest in HungaroControl (1.62 min) followed by Austro Control/ Austria (1.58 min), DFS/Germany (1.44 min) and DSNA/France (1.2 min).

Average horizontal en-route flight efficiency at EUROCONTROL level remained relatively constant over the past five years with a slight deterioration in 2019. The efficiency of actual trajectories decreased by 0.1 percentage points to 97.2% in 2019.
