EUROCONTROL Monthly Briefing provides you with an overview of how the network is performing during the busy summer season.

July 2025

The European aviation network demonstrated improved performance in July 2025 with a growth in traffic of 3% compared to 2024, but en-route delay down by 31%. En-route delays due to capacity, staffing and weather were down respectively by 39%, 16% and 33%, demonstrating the benefits of improved planning, coordination and consistent network procedures across the European airspace. However, delays remained above target levels, causing ongoing disruption for passengers and airlines.

The focus must remain on delivering improved August 2025 performance. The EUROCONTROL Network Manager will further strengthen implementation of network measures, of capacity management scenarios and weather management scenarios and, in this context, the proactive support of all ANSPs has been requested. 

Preparation for the 2026 Summer season has already started in order to benefit from the lessons learned from July 2025, with a focus on the same network priorities, but with enhanced attention to:

• significant enhancements of strategic network measures and procedures, addressing both weather and capacity management,
• strategic preparation of the sector opening schemes and related staff availability, 
• airspace and technological modernisation,
• strategic sector capacity increases benefitting from the above.

More information on traffic numbers, delays, punctuality, and performance of different areas of the Network can be found in the Monthly Briefing.
