Gstaad is a small ski town with only one street, so it does not have its own airport. The closest airport to Gstaad is in Geneva, 160 km away.
Geneva Airport's website can help you find out when your flight will land, as well as a list of charter flights and basic rules for transporting luggage and personal baggage.
A map of Geneva Airport, which can also be found on the airport's official website, can help you find out where the terminals, waiting and rest areas, check-in, restaurants, stores, medical facilities, and parking lots are located.
In addition, the airport has two separate sectors - Swiss and French - which allow the French to use the airport without going through customs. It is also home to the headquarters of the Airports Council International and the European headquarters of the International Air Transport Association.
