N673FX is a 2017 Gulfstream G650, registered to Buster Aviation INC 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 483 legs on 226 days, about 293,134 nautical miles. That is 112% more than the median Gulfstream G650 in U.S. charter service (28 airframes tracked), which puts it among the harder-working examples of the type. It touched 135 airports but keeps returning to the same city pairs: 60% of legs repeat a route already flown in the year.
