Flight delays in Greece increased by 63%: the airline market requires urgent action

At the height of the tourist season, Greece is again faced with increasing flight delays. Eurocontrol records +63% compared to last year and 13% of delays across the entire European network.

Greek airports are once again entering the peak tourist season with flight delays, passenger complaints and a dispute between airlines, air traffic control and civil aviation. Delays related to Greece are up 63% compared to last year, according to Eurocontrol.

The problem did not arise suddenly. “Athens News” back in January wrote that a failure in the communication system actually paralyzed departures and arrivals throughout the country: FIR of Athens was closed from 9 am. The failure then affected radio communications and showed how vulnerable the air traffic control infrastructure remains.

Later, the Athens News separately examined that air traffic controllers had been warning for years about outdated systems and the risk of “aviation Tampi.” FIR of Athens and the real collapse of the “executive state”. In May, air traffic controllers again reported communication outages and demanded system upgrades. ΥΠΑ. Greek air traffic controllers sound the alarm due to communication outages.

In June, the topic returned with delays at Athens airport: air traffic controllers and airlines blamed the civil aviation authority for its inability to properly cope with the flow of flights. Air traffic controllers and airlines blame civil aviation authority for delays.

What’s happening now

According to Keep Talking Greecean emergency meeting was scheduled at the beginning of July with the participation of all major parties: HCAA, ACAA, Athens International Airport, AEGEAN and SKY express. The goal is to find a way to stabilize the situation during the peak tourist season.

The airline market is alarmed by the sharp increase in delays. According to Eurocontrol data cited by Greek media, Greece was among the worst countries in Europe in terms of meeting schedules and gives about 13% general delays in the European aviation network. For a country that lives on tourism, this is not a small thing, but a blow to its reputation. A tourist can forgive the heat, crowds and expensive coffee. But he usually remembers five hours at the airport with the tenderness of a brick.

Passengers and airlines reported that some flights were delayed for several hours. As an example, the Greek media cite a flight from Athens to Milan on July 5, which was delayed by approximately 5 hours. However, the HCAA insists that the average delay in an Athens FIR is only 2.26 minutes per flight.

Why do numbers argue with each other?

It’s important to understand the difference between the average and the actual passenger experience. An average delay of 2.26 minutes may look reasonable on the report, but it does not cancel flights that are 3, 4 or 5 hours late. Statistics, as usual, knows how to be polite where the person at the boarding gate is already talking to the socket.

HCAA says delays at El. Venizelos” related to air traffic control decreased by 31.77%and the average delay in the Athens FIR was 2.26 minutes. Writes about this Protothema.

But Eurocontrol points to a different picture. In its report for the 25th week of 2026, the organization noted that Greece gave 14% of all en-route network delays, of which about 9% occurred at Athens ACC and about 4% at Makedonia ACC. Reasons: capacity, staffing and additional complexity due to changes in traffic flows associated with the Middle East crisis. Eurocontrol Flash Briefing, Week 25.

Where are the bottlenecks?

According to Eurocontrol, Athens and Thessaloniki bear the brunt, with Athens ACC and Makedonia ACC the two key sources of delays associated with Greek airspace. Eurocontrol reports also highlight the impact of the Middle East crisis: some flows are changing routes, which increases the complexity of traffic management in the region.

Airlines, according to Greek media reports, believe that the problem lies primarily in air traffic control. They claim that they schedule flights within the capacity set by aviation authorities and do not exceed the limits. But when one flight is delayed, the delay is carried further down the chain: the plane does not have time to complete the next leg, the crew is behind schedule, and passengers are late for transfers.

This is how the domino effect works. One glitch in Athens can ruin the schedule of not just one flight, but several subsequent routes. The plane, as it turns out, does not teleport to its next departure, although schedules sometimes pretend that physics is just an opinion.

Why is this dangerous for the season?

The summer of 2026 is already under high load. HCAA says traffic reached 4 July 4,925 flightsexceeding the 2025 high of 4,916 flights recorded on August 10. Writes about this Euronews Travel.

For the tourist season, delays mean more than just irritation for passengers. These are additional costs for airlines, disrupted connections, complaints, compensation, pressure on airport services and deterioration in the image of the destination. Especially if delays are repeated on routes through Athens, Thessaloniki and island airports.

At the European level, Greece was in the same group as France and Spain among countries with noticeable delays in June. But for Greece the consequences are especially sensitive: aviation is directly linked to island tourism, where the delay of one flight often drags down ferries, transfers, hotels and the first day of vacation, which turns into meditation on the departure board.

What the authorities say

Greek civil aviation says delays are real but are being exacerbated by seasonal demand and geopolitical changes that have altered flight flows in the wider region. According to this version, we are talking not only about internal problems, but also about external load on the network.

However, this argument does not remove questions about the state of the system itself. If air traffic controller complaints, communication failures, delays in Athens and dependence on outdated solutions are recorded for years, then the Middle East crisis becomes not the cause of all problems, but a stress test that shows weaknesses.

Athens News has already written about the conflict at El. Venizelos” back in September 2025, when delays continued for the second day in a row and were accompanied by a dispute between management and air traffic controllers. Second day of delays at El. Venizelos”.

Main conclusion

Flight delays in Greece in the summer of 2026 can no longer be attributed solely to the peak season. Eurocontrol points to capacity, staffing and changing flows due to the Middle East, while airlines talk about air traffic control problems.

HCAA responds that the average delay in an Athens FIR is only 2.26 minutes and that in June the situation in El. Venizelos” has improved. But passengers and airlines are seeing the other side: hours-long delays on individual flights, scrambled schedules and a domino effect across the entire network.

If authorities want to save the season rather than the report, they will have to address not only operational delays, but also an old problem: systems modernization, staffing adequacy, flow management and trust between air traffic controllers, HCAA, airports and airlines. Tourism does not like uncertainty. And a passenger who arrives in Greece after five hours of waiting usually begins his vacation not with delight, but with the desire to find the culprit. And, what is unpleasant for the bureaucracy, sometimes he is right.
