Of course, not all aircraft are scrapped as soon as their operating airline is finished with them. There is a strong trade in secondhand aircraft, and many airlines are willing to purchase a used aircraft rather than a much more expensive new one. And in less regulated countries, looser maintenance and safety requirements can extend the life of aircraft that have become too costly to continue service elsewhere. Even aircraft such as the A380 have a secondhand market. One retired aircraft from Singapore Airlines was sold to charter airline Hi Fly. However, its use was fairly limited, and the airline confirmed it would be retiring the type (again) at the end of the current lease period.
