Hello! For those considering private air travel to Sion, especially during peak seasons, I’d recommend looking into private jet charter. Sion Airport is particularly busy during the winter months with many heading to nearby ski destinations. However, there’s substantial activity in summer too as travelers explore hiking trails, the local vineyards or attend events like Montreux Jazz. Consider the efficiency and convenience this offers over commercial options when you’re travelling. I found Private jet charter Sion to be a reliable provider, offering various options to suit different needs. Planning private air travel into Sion ahead of time, is beneficial considering the demand at peak times.
