A banker's day trip, or the way to the Engadin
Farnborough to Zurich is 430 nautical miles, 495 statute miles; from London City it is about 20 nm shorter. Every cabin flies it non-stop in about an hour and a half, so the choice of aircraft follows the party and the luggage, not the range.
Switzerland is an hour ahead of London all year. Leave London City at 7.30 am and you land in Zurich at about 10.05 local time, at Paradeplatz before 11; leave Zurich at 6 pm and you are back in London at about 6.35 pm, London time. Meetings in the city, in Zug or on the lake fit in one day.
In winter Zurich is also the gateway to Graubünden: Davos and Klosters are about two hours by car, and a light or midsize jet can fly on to Samedan, ten minutes from St. Moritz, in daylight.
Which London airport to leave from is set out in our guide to the private jet airports in London: FBOs, customs and curfews, side by side.
