Grenoble Alpes Isère Airport (IATA: GNB, ICAO: LFLS) is an international airport serving Grenoble, the capital of the Isère department in southeastern France. Situated approximately 45 kilometres northwest of Grenoble city centre, near the town of Saint-Étienne-de-Saint-Geoirs, the airport sits in the Bièvre plain surrounded by the Alps. The airport primarily serves leisure and seasonal traffic, with strong demand from skiers and winter sports enthusiasts heading to nearby Alpine resorts such as Alpe d'Huez, Les Deux Alpes, and Chamrousse. Traffic volumes are notably higher during the winter ski season. Grenoble hosted the 1968 Winter Olympics and was a venue city for the Paris 2024 Summer Olympics football events. Passenger numbers at GNB are modest compared to major French hubs, typically handling under one million passengers annually, though exact figures vary by year and seasonal patterns.
