Paying a flat rate for unlimited usage as the name implies, uses a business model where clients pay a flat rate, and then the jet is made available to them for the duration that payment lasts. This model makes it possible for a client to pay a certain amount for unlimited access and usage to a jet, or a fleet of jets for the duration. This model has been discontinued by most private jet hire companies because clients have exploited the usage in the past. This model now employs a fair usage policy.
