An FAA Part 135 certificate is the approval a company needs to fly on-demand charter for hire in the United States. Before issuing it, the FAA reviews the company's manuals, pilots, training, maintenance programme and every aircraft it adds, and its inspectors keep auditing the operation. An aircraft flown privately under Part 91 cannot legally be sold to you as a charter. Altivo Jets books flights only with licensed operators and names the operator on every quote.

About Neptune Aviation Services
Neptune Aviation Services is based in Missoula, Montana and has been a primary provider of airtankers to the US Forest Service for more than 25 years. Its BAe 146 jet airtankers drop retardant on wildfires across the West, and it reports 99 percent aircraft availability, which it credits to its winter maintenance programme.
Beyond firefighting, Neptune flies charter in Twin Commander turboprops, runs air attack missions, a flight school and an FBO, and offers general aviation maintenance with avionics as an authorised Garmin dealer, a machine shop and non-destructive testing.
For travellers to western Montana, Neptune's Twin Commanders offer charter from Missoula, while its airtanker fleet is among the most important in American wildfire fighting.
