A Mykonos chauffeur service is pre-arranged private transport with a professional driver, at a price settled before you travel, delivered by a licensed EIX operator: in Greek law an Epivatigo Idiotikis Chrisis, a private-use passenger car with driver, the limousine licence. Under Law 5290/2026 an EIX can only be hired through a written contract registered in the Ministry's digital register before the trip starts, naming the pickup point and the start and end times. On Mykonos the minimum hire from 1 April to 31 October is 30 minutes with a minimum fare of €36, and 3 hours the rest of the year. RYDES posts that contract for you, whether the booking is a JMK airport transfer, an hourly car service for an evening out, or a black car to a lunch reservation at Psarou.
That timed structure is the honest answer to a question people ask: why does a 5 km ride cost what it does. A Greek chauffeur transfer is legally a timed hire, so even a short airport run is priced as at least the legal minimum, and for the length of the contract the car cannot be hired to anyone else. What you get in return is a Mykonos car service that is not part of the queue at the New Port, a named chauffeur rather than a stranger offering a lift in the arrivals hall, and a price that already holds the 13 percent VAT and any airport fee owed for collecting you. Treat it as a taxi alternative in the hours when the island's taxis are simply all busy.
The same reservation covers the whole island. JMK to Mykonos Town and JMK to the New Port are the shortest runs, JMK to Ornos and JMK to Platis Gialos reach the south coast, and JMK to Kalo Livadi goes furthest east. Private transfers handle ferries from Athens and onward hops to Santorini, and firms bringing incentive groups or launches to the island can settle everything on corporate travel accounts.
