Operators can edit and update a transient base for their private jets. When an aircraft is available for charter in any other airport than its home base, operators can let brokers know and increase their selling opportunities.
On the other hand, brokers might find this option very attractive in some cases. As an example, an american private jet available for charter in Europe would probably quote lower than the same model owned by an european company, due to the flying costs per hour and the currency exchange rates.
