As a frequent flyer, I have had the pleasure of using Aéroport de sion multiple times, and I must say that I am impressed with their service. The airport is clean, staff is friendly, and they have a good selection of shops and restaurants. The check-in process is smooth and efficient, and the security procedures are thorough but not overly invasive. Overall, I would rate Aéroport de sion as excellent.
