The company was formed in 2005^[3] with the purpose of operating turboprop commuter aircraft, with the initial fleet consisting of 1 Cessna Grand Caravan aircraft and 3 Beechcraft 1900C aircraft.^{[citation needed]}

In January 2018, the South African Civil Aviation Authority withdrew the Certificate of Airworthiness for 12 of the airline's aircraft due to allegedly unqualified personnel certifying the aircraft as airworthy.^[4] It was subsequently forced by the authorities to suspend operations in late 2018.^[5] The airline successfully launched a High Court challenge and the grounding was overturned. The CAA then again grounded the Airline in January 2019 and CemAir challenged the decision before the Civil Aviation Appeal Committee. On 29 April 2019, the CAAC issued a judgement in favour of the airline, calling the CAA's actions "irrational, arbitrary, unreasonable and procedurally unfair" and "factually wrong."^[6][5][7][8]

In January 2021, CemAir signed an interline agreement with Ethiopian Airlines.^[9]
