London.

London is the busiest private-aviation market in Europe, drawing finance principals, sovereign wealth, Gulf royalty and entertainment names year-round. The calendar never really pauses: Wimbledon and Royal Ascot in summer, the autumn deal season across Mayfair and the City, Chelsea Flower Show in May, and a steady flow of board meetings and family-office visits. Discretion, slot availability and fast customs clearance are what buyers pay for here.

Farnborough (FAB/EGLF) is the region's dedicated business-aviation airport, roughly 35 miles southwest with a single 8,000-ft runway, elegant terminals and no scheduled-airline congestion. Luton (EGGW) offers the most heavy-jet capacity and 24-hour operations north of the city, while Biggin Hill (EGKB) is the closest field to Canary Wharf and the City with helicopter transfers. London Heathrow (EGLL) accepts business jets by prior arrangement but slots are scarce and costly. Expect 45-75 minutes by car into central London, or a 10-15 minute helicopter hop from Biggin Hill.
