N661FX is a 2018 Gulfstream G650ER, registered to Copperwood Asset Management LP of Cleveland, OH. It works in Flexjet's floating charter fleet: on the Part 135 certificate (J7SA), and positioned wherever the next trip starts rather than kept at one airport. In the twelve months to 7 September 2026 it flew 341 legs on 155 days, about 192,798 nautical miles. That is 124% more than the median Gulfstream G650ER in U.S. charter service (64 airframes tracked), which puts it among the harder-working examples of the type. It touched 110 airports but keeps returning to the same city pairs: 61% of legs repeat a route already flown in the year.
