Tourist Surge Overwhelms Athens Air Traffic System, Prompting Major Upgrade

Athens' air traffic controllers are confronting unprecedented pressure as summer tourism drives daily flights to roughly 2,700, compared with the typical 1,000-1,500 in off-peak months. The surge reflects a 23 percent rise in arrivals over the pre-Covid peak, while the broader southeast European airspace has grown about 40 percent since 2019. A January communications breakdown that shut Greek airspace highlighted the fragility of existing systems.

Consequently, a €300 million renovation program was announced, featuring digital communication upgrades and radar replacement, with work beginning in mid-August and expected to finish by 2028. Staffing remains a challenge, with 154 controllers on duty against an estimated need for 250, despite hiring 92 new staff in 2025 and 77 in 2026. Controllers report double the usual aircraft queues, leading to significant delays and safety concerns.
