Yep,

Crew Shedulers, aircraft schedulers, dispatchers, mx control, owner services -- just like a real fractional. A good deal of Flexjet's fleet is on Jet Solutions, LLC Part 135 certificate. Ops are conducted under both 91 and 135.

Dispatchers prepare flight plans, weather briefings, and (on request) prepare runway analysis. Flight plans are filed on a limited basis due to so many changes through out the day left many filed flight plans unused. ATC used to constantly call ops and chide them for having so many garbage plans in the system. Therefore, the filing of the prepared plans usually fell onto FOs.
