Sion Airport is a regional airport located in the canton of Valais in southwestern Switzerland, serving the city of Sion and the surrounding alpine region. Situated at an elevation of approximately 1,585 feet (483 meters) above sea level, it operates within a dramatic mountain environment that influences flight operations and weather conditions.
The airport handles a mix of general aviation, charter flights, military operations, and limited scheduled commercial services, particularly during the winter ski season when demand increases significantly. It serves as an important access point for ski resorts in the Valais, including those in the Four Valleys area.
Sion Airport also hosts an air base for the Swiss Air Force, making it a dual-use civil-military facility. The airport has periodically sought to expand its commercial offerings, though its relatively remote location and alpine operating environment present ongoing logistical challenges.
