My wife and I visited the Swiss Air Amsterdam Office last month to inquire about flight upgrades. Although we were unsure of the procedure, the personnel made it simple for us. They assisted us with the payment and went over our options. The woman behind the counter smiled warmly and was very courteous. She put us at ease. We received assistance immediately, and the office was not overly crowded. Everything went smoothly from beginning to end. We thought our treatment was excellent. Customer service at Swiss Air is excellent.
