Net Jet seems to be doing pretty well:

'For more and more deep-pocketed people who don't want to fly commercial, owning part of a private jet is better than owning the whole thing.
Wealthy travelers who tried charter flights during the pandemic have upgraded to be able to book a flight in as little as four hours, according to Richard Koe, managing director of WingX, an industry analysis firm. And business travelers increasingly want anonymous flights, he said, to avoid revealing potential deals to sleuths who track corporate jet movements.
'Some people moved up into fractional programs, some people moved down,' Koe said. 'The result is you've got these operators doing better than ever.'
...
Fractional operators ' dominated by Berkshire Hathaway Inc.'s NetJets and Flexjet ' saw a 5.2% increase of flights in the first nine months of this year even as charter aircraft flights fell 6.4%, according to WingX. In the past four years, the growth of fractional flights has also outpaced those by charters and corporate-owned aircraft.'
