For Week 33 (11-17 August 2025):
Traffic: During Week 33, there were 35,119 daily flights, slightly below the previous week, +4% vs 2024, and +2% vs 2019 levels.
ATFM delays: Averaged 3.3 minutes per flight, a 10% increase vs the previous week (related to more significant weather events), but 48% lower than in 2024. A total of 53,791 flights were delayed by air traffic flow management (ATFM) restrictions, an average of 7,684 flights a day and 22% of all flights.
Arrival punctuality: Down 1.3 percentage points vs Week 32 to 74%, but better than last year by 8.9 percentage points.
Network hot spots:
- France (29% of all delays in the network): Affected by ongoing capacity and staffing issues.
- Germany (12% of all delays in the network): Affected mostly by capacity issues and weather.
- Greece (10% of all delays in the network): Affected mostly by staffing issues.
- Spain (10% of all delays in the network): Affected by capacity issues related to high 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 134K delay minutes).
Actions to be taken: Brest, Marseille, Reims and Beograd ACCs will need to revise 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 affected significant parts of the network, most notably on 16 and 17 August. The scenarios pre-agreed between the ANSPs and the EUROCONTROL Network Manager (NM), moving traffic away from areas of forecasted convective weather, saved 72K minutes of delay across the week, 25% of the total weather delay in Week 33.
