Athens air traffic control strained by tourism surge, safety concerns mount

In the control room at Athens, the radar screens glow with green arrows—each one a plane full of people waiting to land or take off. During the summer months, these arrows multiply until they crowd the display like a traffic jam rendered in light. Olga Toki, who oversees the air traffic controllers' union in Greece, watched the screens fill up one August afternoon and said what everyone in the room was thinking: the sky was full. There was nowhere left to put another plane.

The numbers tell the story plainly. In the quieter months, Greek airports handle somewhere between 1,000 and 1,500 flights each day. In early July, that number jumped to 2,700 flights daily. The surge reflects a tourism boom that has remade Greece's economy and its summers. Last year, 38 million tourists visited a country of roughly 10 million people—23 percent more than visited before the pandemic. They came by plane, and they came in waves.

Across the broader region, air traffic in southeast Europe has climbed about 40 percent since 2019. The Middle East conflict has added another layer of complexity: roughly 300 extra flights now cross Greek airspace each day to avoid the region, representing nearly 6 percent of daily traffic. On top of that, controllers must track Turkish military incursions and drone activity. Greece's geography—positioned between Europe and the Middle East, between NATO and a neighboring country with whom relations are tense—means the workload is not just heavy but intricate.

The system was already fragile before the summer rush began. On January 4th, the communication network linking controllers to pilots failed completely. Controllers could see the planes on their screens but could not hear or speak to the pilots flying them. Greek airspace had to close for hours. Planes were diverted to neighboring countries. The breakdown exposed how thin the margin of safety had become. It was a wake-up call that led to a €300 million modernization program—new digital communication systems, replacement radar, updated navigation procedures. Installation began in mid-August. The work will not be finished until 2028.

The real strain, though, falls on the people in the control room. Greece employs 154 air traffic controllers. The country needs 250. New hires have been brought on—92 in 2025, 77 in 2026—but each one requires five years of training before they can work independently. Giorgos Stamoulakatos, a shift supervisor, described the shortage plainly: they are desperately understaffed every summer.

Areti Anastopoulos has been guiding planes into Athens for more than thirty years. Her voice is known to every pilot who has landed there. On a normal hour, she helps about 20 planes line up for landing. During peak summer, 40 are in the queue. She has had to order planes to slow down mid-approach, to alter their flight paths, to circle and wait—all to prevent collisions. In one hour recently, 33 planes landed. The system is designed for 28. "What we're doing here is a superhuman attempt to keep everyone safe," she said. The word choice was not casual. It was a description of the work as something beyond normal human capacity, sustained through will and experience and the knowledge that a mistake could be catastrophic.

In the terminal, passengers felt the strain differently. Jose Lopez arrived from Barcelona thirty minutes late and shrugged—delays in August were normal. Christos, who parks cars at a major hotel, was less philosophical. Delays had become more frequent than the year before. He had waited seven hours for American clients to arrive. Tourism is Greece's economic engine, Anastopoulos acknowledged. But the equation is simple: more planes without more investment is not sustainable. The modernization program will help, but not until 2028. Until then, the controllers will keep doing work that exceeds what the system was built to handle, and the delays will keep accumulating.
