Grenoble Alpes Isère Airport guide

Grenoble Alpes Isère Airport (ICAO: LFLS) lies mainly in the commune of Saint-Étienne-de-Saint-Geoirs, at an elevation of 397 m, with parts of the site in Brézins, Gillonnay and Saint-Hilaire-de-la-Côte. It is also known as Grenoble-Saint-Geoirs. The site was a military airfield from 1938 to 1966, and the civil airport opened to the public on 16 November 1967, replacing Grenoble-Mermoz. It took its current name in 2016.

The Isère departmental council owns the airport. VINCI Airports ran it under a public service delegation that began in 2009 and ends on 30 June 2026. Edeis Concessions and CB Autocars hold the 12-year contract that follows, from 1 July 2026 to 30 June 2038.

The main runway, 09/27, is asphalt, 3,050 m long and 45 m wide, with a Category I instrument landing system. A 900 m grass strip beside it serves general and leisure aviation. The terminal capacity is stated as up to 1 million passengers a year.

Traffic is seasonal and tied to the ski winter. Most routes link Grenoble with the United Kingdom, and the airport also has flights to other European cities. Passenger numbers grew from 191,195 in 2022 to 260,991 in 2025.
