Sion Airport - Spotting Guide

Sion Airport – Spotting Guide

April 3, 2017 - last modified on January 25, 2025

Sion Airport (IATA: SIR, ICAO: LSGS), is located in the state of Valais near the most well-known ski resorts of Switzerland. The airport was mainly used by the Swiss Air Force but due to the coast reduction of the army, the Air Force has left the base at the end of 2017. Sion is now mostly if not exclusively used by civil and general aviation. Acting only as alternate airfield for the Swiss Air Force or special missions.The traffic is mainly concentrated on business jets and small props from a Pilatus PC12 up to a & BBJ2 or ACJ 320. The peak time is between the 15 December until end of March. Also note that TAG Aviation has a maintenance base therefore all along the year you can expect to see some GLEX, FA7X, GLF4, GLF5, GLF6, E35L etc.

It is very convenient to check the weather before going especially during Winter time. Therefore we recommand you to have a look at the following : Sion Airport Webcam
