Air traffic at Luxembourg Airport was significantly disrupted in the evening of Friday, September 18, 2026. According to Reuters, flights resumed on Saturday morning. The flights had been suspended the previous day due to the presence of unauthorized unmanned aerial vehicles, commonly known as drones. These devices were detected "nearby, then above the airport," according to a statement from the airport. As a precautionary measure, the airport chose to suspend all flights to ensure the safety of passengers and staff. Luxembourg Airport, known as Findel, is the only international airport in Luxembourg. It serves as a hub for the national carrier Luxair and, especially, for Cargolux, one of Europe's largest air freight operators. Therefore, even a closure of a few hours affects both passenger traffic and the transportation of goods. Despite the resumption of flights, delays are still possible this morning; passengers are advised to check the status of their flight with their airline before traveling to the airport. The disruption of flights at Luxembourg Airport was visible on Flightradar24, the website that displays real-time information on commercial or private flights. It was indeed possible to observe the suspension of flights around the airport in the evening of September 18, with no arrivals or departures possible. "Luxembourg Airport continues to closely monitor the situation in coordination with the competent authorities, air traffic control services, airlines, and its operational partners," the airport statement mentions. The origin of the drones was not specified by the airport, reports Reuters. This event, however, echoes the alerts issued by Emmanuel Macron on Friday evening: in response to the increasing number of hybrid attacks on the continent, France is preparing an action plan to secure its strategic infrastructure against drones and cyber threats. This scenario is not new in Europe. In September 2025, several airports on the continent, including Copenhagen and Oslo, had already suspended their traffic after drone overflights. The Danish authorities described these intrusions as a hybrid operation aimed at disrupting critical infrastructure, without formally identifying their origin, a caution that is also evident today on the side of Luxembourg.
