Europe recorded its busiest summer for air traffic on record in 2026, with an average of 35,959 flights per day between June and August, even as the war in the Middle East disrupted established aviation routes and shifted holiday travel patterns across the continent.
Data from the European Organisation for the Safety of Air Navigation, known as Eurocontrol, showed that average daily traffic increased 2.4% from summer 2025. The network reached its highest single-day level on July 10, when 37,640 flights were recorded.
The record traffic came despite extensive disruption to routes connecting Europe with the Middle East. Earlier in 2026, Eurocontrol estimated that the conflict had reduced flights between Europe and the Middle East by 59%, while about 1,150 flights per day were affected by rerouting to avoid conflict zones and closed airspace.
The effects were unevenly distributed across Europe, with traffic declining in some countries while holiday destinations in southeastern Europe experienced strong growth.
Balkans Gain From Shift in Holiday Traffic
Eurocontrol said the conflict influenced the distribution of tourist traffic, with travelers increasingly favoring destinations within Europe that were perceived as less exposed to the conflict.
“This can be attributed to a decline in air traffic in Bulgaria, Hungary, Romania and Turkey, but a strong increase in Albania, Croatia, Cyprus, Greece, Montenegro, North Macedonia, Serbia and Slovenia,” the organization said.
Eurocontrol also highlighted a “continued increase in southwestern Europe.”
The shift was particularly pronounced across the Balkans and southeastern Europe, where several countries recorded substantial increases in air traffic during the summer season.
Fourteen countries recorded their highest-ever daily traffic levels for arrivals and departures. They included Albania, Armenia, Georgia, Greece, Ireland, Italy, Moldova, North Macedonia, Montenegro, Portugal, Serbia, Slovakia, Spain and Türkiye.
The trend also benefited a number of airlines and airline groups. Record traffic was recorded by Aegean, Air Serbia, easyJet, Jet2.com, Pegasus, Royal Air Maroc, Ryanair, Sky Express, SunExpress, Turkish Airlines and Wizz Air.
Greece’s Air Traffic System Faces Capacity Pressure
Greece was among the biggest beneficiaries of the shift in European holiday traffic, but the surge also placed substantial pressure on its aviation infrastructure.
Record passenger numbers at Greek airports pushed the country’s air traffic control system toward its capacity limits during the peak summer period.
The increase in southeastern European traffic reflects a broader redistribution of aviation flows following the disruption of routes associated with the Middle East conflict. While countries such as Bulgaria, Hungary, Romania and Türkiye experienced lower traffic, demand increased sharply across alternative destinations in the Balkans and the Mediterranean.
Punctuality Improved Despite Record Traffic
The record volume of flights did not result in a deterioration in overall punctuality. Arrival punctuality reached 72.6%, 1.2 percentage points higher than in summer 2025.
Air traffic flow management, or ATFM, delays also declined by 17%, falling to an average of 3.27 minutes per flight.
Still, congestion and capacity constraints remained a major problem. Approximately 681,000 flights were delayed by ATFM restrictions during the summer, equivalent to about 7,400 flights per day and 21% of all flights.
Capacity and staffing issues accounted for 49% of en-route ATFM delays, while severe convective weather was responsible for 43%. Industrial action accounted for just 1%.
France was the largest contributor to delays linked to air traffic management problems, accounting for 32% of the total.
European Network Faces Continuing Capacity Challenges
Eurocontrol’s data also highlighted persistent capacity challenges across Europe’s air traffic control network.
Of the continent’s 68 area control centers, 45 are currently on track to meet the European capacity target by the end of 2026. Another 10 remain on track but continue to face pressure from adverse weather and the Middle East crisis, while 13 are expected to miss the target.
The figures underscore the strain placed on European aviation infrastructure as demand continues to grow while conflict, weather and staffing constraints alter traffic patterns.
Despite those pressures, the summer of 2026 established a new benchmark for European aviation. The combination of record passenger demand, shifting holiday preferences and rerouted aircraft produced unprecedented traffic levels across parts of the continent.
For southeastern Europe in particular, the disruption caused by the Middle East war translated into a sharp increase in aviation activity, reinforcing the region’s position as a major destination for European summer travel.
