Airport contact
Switzerland's only mixed civil-military concession airport (Swiss Air Force reserve base); no standard ILS — special steep IGS RWY 25 approach (day only, qualified crews). Cantonalisation law passed March 2026 but subject to pending referendum. Sion-based Air Mountain declared bankrupt 27 May 2026 — its Calvi/Figari/Alghero/Elba/Saint-Tropez schedules suspended; remaining international commercial service is the weekly Helvetic Airways Palma de Mallorca rotation (5226/5227, 28 May–8 Oct 2026, sold by Buchard Voyages).
