Farnborough is a business-aviation airport and nothing else. There are no scheduled airline services, no check-in desks and no arrivals hall in the usual sense: one terminal, run by the airport itself as the handling operation, looking after private and charter aircraft. It sits in north-east Hampshire, a short run from the M3, with customs, immigration and security screening done on site, so an international arrival is cleared in the building and walks out to the car rather than to another queue.
Unlike a commercial airport, it keeps hours. Its planning permission allows flying between 7am and 10pm on weekdays and between 8am and 8pm at weekends and on bank holidays, with none at all on Christmas Day or Boxing Day. For the car this matters at the end of the day. A jet that leaves Geneva or Nice late and cannot make the window will land somewhere else, and the chauffeur needs to be sent there rather than left at a terminal the aircraft is no longer coming to.
Flight tracking works differently here. The tracking that follows arrivals at the airline airports is built on airline flight numbers, and a private jet usually does not have one: it flies under its registration, or an operator's callsign. A Farnborough pickup is therefore timed from the operator's schedule and kept current by people rather than by a data feed. Give us the tail number, the operator or broker, and a contact who will know when the aircraft is wheels-up. The control room stays in touch with them, and a revised arrival time moves the car.
The car joins the M3 at junction 4. Where it meets the M25 there are two ways in: on to the end of the M3 and the A316 through Richmond, or round to the M4 and in along the A4. Which is quicker depends on the hour. The City and Canary Wharf are the same journey with the width of central London added, and in the weekday rush that last stretch is where the time goes. The airport describes the drive to central London as under an hour, which is fair outside the peaks and optimistic inside them.
Private flying often comes with a principal who values discretion, or a protection team who insist on it. Every chauffeur is SIA-vetted and named the evening before with his photograph and registration: what an airport, a family office or a security detail wants in hand before a car goes near an aircraft.
