Schedules services under the 'Fly Tiwi' brand commenced in November 2008, offering flights on routes between Darwin and Nguiu on Bathurst Island and connecting Darwin with Pirlangimpi and Milikapiti on Melville Island several times per day. In January 2009 a third route was added providing daily services to South Goulburn Island and the community of Minjilang on Croker Island, and in May began services to Ramingining three times per week, adding a fifth route to Gapuwiyak twice per week in early 2010. Fly Tiwi, since 2017, has been servicing these routes daily from Monday to Friday. On 29 June 2010, Fly Tiwi inaugurated services to Tennant Creek twice per week, but has since discontinued this service.  From mid-2017, Fly Tiwi added another route servicing the community of the Milingimbi Island, which it also services Monday to Friday.
In February 2012, Fly Tiwi was one of a number of aviation companies that participated with the Northern Territory Police in 'Operation Bristol', a crackdown on the trafficking of illegal drugs to remote communities which resulted in the seizure of cannabis and kava with an estimated street value of over $300,000.
As of 2017, Fly Tiwi offers services to the following destinations:
- Gapuwiyak (Lake Evella)
- Milikapiti (Snake Bay)
- Minjilang (Croker Island)
- Nguiu (Bathurst Island)
- Pirlangimpi (Garden Point)
- Warruwi (South Goulburn Island)
- Milingimbi Island
Flights to and from Darwin International Airport operate out of a dedicated Fly Tiwi terminal located adjacent to the General Aviation apron.
