ESTIMATED VALUE

What N37273 might be worth

Rough range$6.9M to $26M

A rough range for a 2001 airliner, with a middle of about $14M. From Radar's listing-based estimates for airliners of similar engine thrust and age. It is not an appraisal and knows nothing about N37273 itself: total time, engines, condition, equipment and the logbooks move the price of any one aircraft.
