Over 1 million flights in July in Europe (+7%), but traffic affected by extreme weather

Europe experienced extreme weather in July and the weather-related ATFM delay during this month was over two and a half times the 2022 figure. The main impact has come from convective weather (thunderstorms etc.), notably in Germany, Hungary and Serbia. At airports, the largest weather delays have been at Frankfurt, Gatwick and Munich.

Overall, without the weather element, ATFM delays per flight reduced by nearly a quarter to 2.5 minutes per flight (despite traffic growing 7%). When the impact of the adverse weather is included, they increased marginally from 3.9 to 4.1 minutes per flight.

ATFM delays make up only a small part of the total delays experienced by the passenger. Looking at overall punctuality (which also reflects reactionary (knock-on) delays, airline scheduling delays and delays on the ground), this was slightly better than in July 2022, despite more traffic and the impact of adverse weather – albeit still below the 2019 level.

The improvements in Network performance in July show that close cooperation between all operational partners is delivering good results. Looking to August, EUROCONTROL will continue to do its utmost in full partnership with operational stakeholders to minimise delays and improve overall punctuality.

Background

A series of actions were identified by EUROCONTROL together with the airlines, air navigation service providers, military, and airports to address the challenges. These include:

• Prioritising First Rotation
• Flight Plan Adherence
• Realistic schedules, including turnaround times
• Delivering agreed capacities

These actions have played a major role in ensuring that the European air traffic network has delivered a strong performance so far this summer.

The EUROCONTROL Network Operations Plan, which is a weekly rolling seasonal assessment of the situation in the network and how it is being addressed identifies some areas where available capacity is currently below anticipated demand. This is done to allow operational stakeholders in those areas to make the necessary adjustments to try to address any shortfall. It is not a predictor of specific delays in those areas.

Key figures

• There were 1,018,890 flights overall in the European network compared to 951,099 in July 2022, an increase of 7%.
• ATFM delays per flight have increased by 6% compared to July 2022. This rise was as a result of an increase in weather delay per flight – from 0.7 minutes to 1.7 minutes.
• ATFM delays were 4.1 minutes per flight in July 2023.
• Comparing July 2023 with July 2019, total ATFM delays were down by 4%.
• Arrival punctuality (within 15 minutes of scheduled time) – which reflects all causes of delay, not just ATFM – was two percentage points better than in 2022 (at 63.6%) but lower than in 2019.
