Discreet ground transport for a visiting executive is mostly a matter of who knows what, and when. The fewer people and systems that hold the itinerary, the less there is to leak, so the simplest setup is one desk, one booking per trip and written confirmation of every detail.
Book through the single 24/7 desk, by phone or text or through the online booking, with the visiting executive's flight number in the flight number field. The desk tracks the flight and times the pickup to actual landing, so you are not relaying delay updates from another time zone. If the itinerary changes while the executive is in the air, one message to the desk updates the chauffeur.
Ask for an NDA when you book. NDAs and confidentiality agreements are available on request for government and VIP clients, and the desk arranges them before the trip. Chauffyr does not publish client names, and on discreet bookings the name board is suppressed by default.
Send the principal's preferences with the booking, such as vehicle class by city, meet & greet, and anything the chauffeur should or should not mention, and they are confirmed in writing. For a visiting executive with several stops, an hourly booking keeps one chauffeur and one car for the day; Sedan and SUV hourly bookings have a 4-hour minimum.
For repeated visits, a corporate account adds consolidated USD invoicing and a named account manager, so every trip for every principal sits on one bill instead of an executive's personal card. Outside Napa and the San Francisco Bay Area, vetted affiliate partners run each trip, coordinated by the same desk.
