Not guaranteed as a part of a traditional fractional jet program, interchange rates account for the differences in both operational and acquisition costs between two aircraft and are calculated by multiplying the number of hours flown by the interchange rate of the aircraft requested. With Unlimited Access, “downgrading” to an aircraft with lower operating expenses is 100% guaranteed and significant cost savings can be achieved. All aircraft currently within our U.S.-based fleet are eligible, including the Phenom 300 (light-cabin aircraft), Praetor 500 (midsize-cabin aircraft), Challenger 350 (super-midsize-cabin aircraft), Praetor 600 (super-midsize-cabin aircraft) and Gulfstream G450 (large-cabin aircraft).
