A Frankfurt chauffeur service is a private car booked in advance at a fixed euro price and driven by a licensed chauffeur operator holding a Mietwagen concession under the Personenbeförderungsgesetz (PBefG), the federal Passenger Transport Act, with concessions in the city enforced by the Ordnungsamt der Stadt Frankfurt am Main. Because it is a Mietwagen and not a taxi, the car cannot be stopped on the street and does not queue at ranks. The vehicle class, the chauffeur and the total are agreed before the journey, whether that is a Frankfurt Airport transfer, an hourly car service in Frankfurt or a black car to the Bankenviertel.
Where it earns its place is predictability. A taxi meter keeps running while the Frankfurter Kreuz backs up beside the airport, and app prices can climb on the first morning of a big fair. A reserved Frankfurt car service booking does neither: the figure you accept already holds the 19 percent VAT, any short-stay or car park charge at the airport for your pickup, and the waiting allowance. Germany has no car toll on its Autobahns and Frankfurt has no congestion charge, so there is nothing else to add. For a direct side-by-side, see the taxi alternative in Frankfurt.
The same reservation reaches well past the city line. Terminal 3 to the Bankenviertel without the people mover, FRA to Messe Frankfurt on fair days, FRA to Bad Homburg and the Taunus, a transfer between FRA and Hahn, and FRA to Ramstein for travellers heading to the air base. Firms with people landing every week use corporate accounts in Frankfurt for central invoicing on the same fleet.
