Flight delays rise as Middle East rerouting increases pressure on Greek airspace
Flight delays are increasing across Greece as the summer travel season gathers pace, with air traffic rerouted from the Middle East adding significant pressure to the country's airspace, according to the latest data from Eurocontrol.
The conflict in the Middle East has disrupted established flight corridors, forcing airlines to divert routes and increasing traffic density over southeastern Europe. As a result, the Athens Flight Information Region (FIR) has become a key transit corridor linking Europe with the Eastern Mediterranean and Asia.
According to Eurocontrol data covering the first half of June, Greece ranks among the European countries most affected by en-route Air Traffic Flow Management (ATFM) delays, alongside Cyprus, Albania, Serbia and Montenegro.
Airspace congestion intensifies
Greece accounts for 14% of total en-route ATFM delays across the European network, with 9.5% attributed to the Athens Area Control Center and a further 4.4% to the Macedonia sector.
Unlike several other European countries, where delays are mainly linked to staffing shortages and air traffic control capacity constraints, Greek airspace is also experiencing the impact of increased overflight traffic diverted away from Middle Eastern routes.
The additional traffic has significantly increased operational complexity for air traffic controllers managing one of the region's busiest transit corridors.
Delay times jump despite broader European improvement
Eurocontrol said average delay times in Greek airspace have risen by 82% compared with the same period last year, while the Athens Area Control Center is currently falling short of performance targets outlined in the Network Operations Plan because of higher-than-expected traffic volumes.
Across Europe, however, overall network performance has improved despite rising demand. Average daily air traffic reached 34,983 flights during the reporting period, up 1.2% year-on-year.
Average ATFM delays across the continent fell by 29% to 2.3 minutes per flight, while arrival punctuality improved to 76%, according to the agency.
France and Spain remain biggest congestion hotspots
Eurocontrol data showed that France and Spain continue to account for the largest share of delays in the European network, representing 28% and 23.2% of total congestion respectively.
The delays in those countries are primarily linked to capacity limitations, staffing pressures and ongoing upgrades to air traffic control systems.
For Greece, however, the combination of record summer tourism demand and traffic rerouted from the Middle East is creating an additional challenge, raising the likelihood of longer delays during the peak travel season.
