ESTIMATED VALUE

What N840SY might be worth

Rough range$30M to $81M

A rough range for a 2017 airliner, with a middle of about $49M. From Radar's listing-based estimates for airliners of similar engine thrust and age. It is not an appraisal and knows nothing about N840SY itself: total time, engines, condition, equipment and the logbooks move the price of any one aircraft.
