What Sion Airport does
Sion Airport (Aéroport de Sion, ICAO: LSGS, IATA: SIR) is a municipal international airport located 2.5 km southwest of Sion city center in the Valais canton of Switzerland, owned and operated by the City of Sion (Ville de Sion) since its founding in 1935. The airport operates a 2,000-meter runway supporting both IFR and VFR traffic, equipped with an IGS (since 1991) and an RNAV (RNP 0.3) GPS approach on runway 25 (since February 2016), and serves as a gateway for leisure travel to Alpine ski resorts and Mediterranean destinations, business and private aviation, helicopter transfers, flight training, gliding, parachuting, and heli-skiing.
The airport generates revenue from five streams: airport charges and fees, fuel sales (JET A1, AVGAS 100LL, UL 91, and SAF, with tiered fuel accounts and four accepted fuel cards), ground handling delivered through three agents (Sion Airport in-house, Signature Flight Support, Alpine Jet Service), hangar and facility rental (for aircraft up to 77,000 kg including A320-type), and parking services across three lots totaling 260 spaces. Its core technology is aviation infrastructure rather than software, anchored by precision approach systems and a proprietary pilot qualification regime (Type A online and Type B simulator-based certifications, valid 12 months).
Commercially, Sion runs a partner-led go-to-market: scheduled seasonal flights to Mediterranean destinations are operated by Helvetic Airways (Palma de Mallorca) and Air Mountain (Alghero, Île d'Elbe, Calvi, Figari, St Tropez), distributed through Buchard Voyages, while event-driven helicopter traffic serves the WEF in Davos and the Montreux Jazz Festival. In 2025 the airport handled 43,888 flights and 39,587 passengers, with approximately 30-40 staff and a currently vacant Director position. Sion distinguishes itself as the first Swiss airport to market Sustainable Aviation Fuel and maintains heritage branding tied to Hermann Geiger, 'The Glacier Pilot'.

- Lugano Airport: Lugano is a Swiss regional airport with a similar passenger volume tier, a mix of leisure charter and business/general aviation, and a comparable role as a secondary access point for southern Switzerland and northern Italian tourism markets.
- Chambéry Airport: Chambéry Savoie Mont Blanc is a French Alpine airport that primarily serves ski resorts in the northern French Alps. It is directly comparable to Sion as a small, seasonal, ski-access gateway with charter and private aviation activity.
- Samedan Airport (Engadin Airport): Samedan/Engadin is another small Swiss Alpine regional airport serving the Upper Engadin and St. Moritz ski region. It is the closest direct comparable to Sion in terms of size, Alpine positioning, seasonal ski traffic, and reliance on business/general aviation rather than mass-market scheduled service.
- St. Gallen-Altenrhein Airport: Altenrhein is a small Swiss regional airport with a mix of business aviation and leisure charter flights serving eastern Switzerland and the Lake Constance region. Its scale, charter-led model, and niche regional role are directly comparable to Sion.
- Innsbruck Airport: Innsbruck is an Alpine gateway airport in Austria serving Tyrolean ski resorts with both scheduled leisure and private/business aviation. It is the most direct international analogue to Sion in terms of ski-resort access positioning, seasonal charter model, and reliance on premium Alpine tourism.
Others
- Jet Aviation: Jet Aviation operates a global FBO and ground handling network serving business aviation. It is comparable to Sion's handling operations (which include Signature Flight Support as a partner) and illustrates the international FBO competitive set that competes for Sion-based business aviation tenants.
Broad incumbents
- Geneva Airport: Geneva is Switzerland's second-largest international hub and is referenced in Sion's own materials because some Air Mountain flights (e.g., St Tropez) route via GVA. It is a broader incumbent in the Swiss aviation ecosystem rather than a direct competitor for Sion's niche.
- Zurich Airport: Zurich is Switzerland's largest international airport and dominates scheduled traffic in the country. It serves as a broad incumbent against which Sion competes for premium Swiss-based leisure and business aviation demand.
