Farnborough to Linate is 532 nautical miles, 612 statute miles, across France and over the Alps. Every cabin flies it non-stop, so the choice of aircraft follows the party and the luggage, not the range. From London City the flight is about 15 nm shorter; from Luton about 10 nm longer.
Italy is an hour ahead of London all year. Leave Farnborough at 8 am and you land at Linate at about 10.50 local time, in the Quadrilatero before lunch; leave Linate at 6 pm and you are back in London at about 6.50 pm, London time. A showroom visit, a lunch and a flight home fit in one day.
Linate is the city's airport, with its own business aviation terminal fifteen minutes from the Duomo. Malpensa, 45 minutes to the north-west, takes the largest cabins and the late arrivals, and is the closer airport for the western shore of Lake Como and Lake Maggiore.
