How access at Farnborough actually works
In the case of Farnborough, it is important that you are more specific rather than reassuring.
Your chauffeur meeting at the business aviation centre is the usual practice that can be arranged in advance with the handling agent. Airside access is another thing. Arranging the arrival of vehicles at the aircraft steps depends on airport security and FBO and requires prior approval and is given on a case-by-case basis. No chauffeur service can promise this in advance, so treat any such promise as a red flag.
If you do receive approval for it, the coordination is done between your handling agent and operator in advance of arrival, and includes all prior permissions needed for entering the controlled area by the vehicle. In case of no approval, your chauffeur will meet you at the business aviation centre and escort you to the vehicle.
Private aviation journeys
Most Farnborough airport transfers will go somewhere particular, not just into town. Onward flights are very common here, and the transfer journey between Farnborough and the airport of choice is one of the standard bookings: if the connection route is going through West London, compare airport transfers to Heathrow.
Private jet and business aviation into the capital represents the second half of the task, and for anyone considering private transport versus a short hop on a scheduled flight, London City airport transfers represent the business transport option closest to the financial district.
Working with multiple vehicle journeys is the norm here in a way it is not at other airports: delegations travelling together, crew separate from the passengers, road show schedules lasting several days, and especially during Farnborough International Airshow season, when vehicles and drivers need to be booked well in advance.
Choosing your vehicle
Business and Standard are the usual classes for private flights, Business XL, the people mover class of the range, handles crews, security groups or families coming together with six bags, while First and Executive classes are what most private aviation customers expect.
Delegations travel in multiple vehicles as a matter of course here, all on one booking and one single contact point.
Multi-vehicle groups form the norm around here as opposed to one minibus.
