There are apps available that allow users to book private jet charters. It is possible to use these apps to book a flight. However, people booking through these apps may end up paying higher prices and may not get the best aircraft for their needs. This is because the algorithm of an app is no replacement for an experienced private jet broker.
A broker knows which operators have which aircraft available and which routes are commonly flown. A broker can also more easily react to fluctuations in prices much more quickly than an algorithm can. Plus, a broker may have a relationship with certain operators that can result in deals that can lower the cost for passengers.
