Me too...

Any party interested in having an aircraft should complete such due diligence regarding their mission requirements before committing to any one solution if the most cost-effective path is desired.

There's a lot of light jet operators (like my company) which utilize the airplane in a manner that makes a comparable light jet fractional share or charter VERY uneconomical...but also own a fractional share or card program for another airframe to supplement their in-house lift or provide additional capabilities when needed (unlike my company).

There's also a lot of light jet users who don't want to "hassle" with operating their own flight department so they utilize charter and/or frax exclusively for the "turn-key" convenience despite its higher price tag; I can think of at least one company local to me that falls into that category.

Bottom line:there are lots of solutions to fit a company or individual's needs depending on their desires for convenience and/or cost.
