You will never, ever take another flight like this. Launched last month, Crystal Skye is the world’s largest private charter jet – a converted Boeing 777 that accommodates just 88 passengers, rather than the usual 300 or so. The first aircraft launched by Crystal Cruises, which until now has focused on offering luxurious experiences at sea, it costs in the region of £43,000 an hour to charter and is unlike anything else in the sky.

The front of this 200LR-type 777 is taken up by a comfortable 24-seat restaurant, bar and lounge that (with apologies to Sir Richard Branson) make the Virgin Atlantic version look like a hot-dog stand. In the rear is a state-of-the-art gourmet galley and a 200-bottle wine cellar said to be the largest on any aircraft, anywhere.
