Generally speaking, if you’re flying a lot of hours a year, it can be worth it to own a jet instead of chartering. Hours of flight time aren’t the only factor that should be considered when deciding whether or not to purchase a private jet. How many hours spent in-flight is important, but so is the type of flying. If the hours are split among multiple people in different locations, owning a single jet wouldn’t fit the needs of the organization.
Owning a jet means that you wouldn’t have to pay per flight, but there are other costs associated with ownership, including maintenance and hangar fees. You would also be responsible for paying the flight crew. If you typically spend a long period of time at the destination, it may end up costing more to fly your own jet than to just book two charters.
