Why don't many VIP airport transfer services in Switzerland list their prices on their websites? If you have used a transfer service (Zurich Airport), can you please tell me how much you paid and what route you took?
When it comes to expensive things and a luxury level of service, prices may not be quoted, but discussed with the customer after contact. However, I can find prices on most chauffeur service websites in Switzerland. Maybe you are interested in a non-standard route and that's why you can't find prices? I contacted "Zurich Airport Limousine" last year when I flew to Zurich for a vacation with my sister. We booked a transfer into the city in a Mercedes S-Class. They have prices for popular routes on their website.
