Since TAG is foreign-owned (Swiss), it can't own more than 25% of any fractional that conducts some flights under Part 135 rules, hence the reason Cessna had to take another 25% share in CitationShares when it launched the Vector Jet Card program (taking Cessna's stake in CS to 75%). TAG could outright own a frax operating solely under Part 91K (no foreign-ownership rules exist for Part 91 ops), but it wouldn't be able to offer jet cards since those flights must be conducted under Part 135 rules.
So...Flight Options would have to eliminate its JetPass program, as well as turning in its Part 135 certificate, before TAG could ever buy a majority share in the frax provider. It could buy a minority stake in FO, but why would TAG do this after Raytheon stiffed the existing FO minority shareholders with its latest recapitalization? Before the recapitalization, Brantley owned about 18% of FO; afterward, that share went down to about 1%, taking its equity stake from about $8M to less than $500,000. That's less than a fifth of what it originally invested in FO in 1998. What a great ROI!!! TAG would be better off just burning a pile of money for heat...
