For Week 36 (1-7 September 2025):
Traffic: During Week 36, there were 35,296 daily flights, slightly below the previous week, +4% vs 2024, and +1% vs 2019 levels.
ATFM delays: Averaged 3.2 minutes per flight — 26% below the previous week, and 34% lower than in 2024. A total of 53,873 flights were delayed by air traffic flow management (ATFM) restrictions, an average of 7,696 flights a day and 22% of all flights.
Arrival punctuality: Up 2.1 percentage points vs Week 35 to 74%, and better than last year by 9.4 percentage points.
Network hot spots:
- France (25% of all delays in the network): Affected by ongoing capacity and staffing issues, and weather.
- Germany (12% of all delays in the network): Affected mostly by staffing issues and weather.
- United Kingdom (9% of all delays in the network): Affected mostly by high airport demand and weather.
Network Operations Plan (NOP) delivery:
- With 3.9% year-to-date traffic growth, en-route ATFM delay so far is 26% better than 2024, with good delivery by all air navigation service providers (ANSPs) in South-East Europe, Central Europe, Italy and Switzerland.
- Most ANSPs are delivering the agreed capacity.
- However, Marseille Area Control Centre (ACC) did not fully provide the capacity planned in the NOP (generating 90K delay minutes).
Actions to be taken: All ACCs revised their plans to align with the NOP for the upcoming weeks. The implementation of capacity management scenarios by EUROCONTROL’s Network Manager Operations Centre (NMOC) will be further amplified and, in this context, the proactive support of all ANSPs will be further requested.
Weather: Convective weather continued to affect significant parts of the network, but to a less severe extent than the previous week. The scenarios pre-agreed between the ANSPs and the EUROCONTROL Network Manager (NM), moving traffic away from areas of forecasted convective weather, saved 80K minutes of delay across the week, 30% of the total weather delay in Week 36.
Industrial action: The on-going industrial action at Beograd ACC has resulted in 48k minutes of en-route ATFM delay during Week 36, again of a similar order of magnitude to previous weeks, but of a level very similar to the other summer weeks when they were related to capacity and weather issues in the context of sustained traffic growth.
