At first appearance, the second-hand business-jet sector looks like a buyer’s market.

First, nearly one in five of the world’s active business jets is currently for sale, according to Brian Foley Associates, the independent business aviation analysts based in New Jersey, while a recent report by JP Morgan put the used jet inventory at 14.5 per cent in March. What analysts agree on is that there are currently about 60 per cent more used business aircraft on sale than there were at this time last year.
