[18] In 2012, Sriwijaya Air begun its planned transition into becoming a full-service carrier; this saw the reconfiguration of its entire fleet to be equipped with a business class cabin to fulfil the Indonesian government's criteria for a full service-carrier.

[27] On 9 November 2018, Garuda Indonesia, through its subsidiary Citilink, took over operations as well as financial management of Sriwijaya Air with a Cooperation Agreement (KSO) mutually agreed upon by both airlines.

The cooperation agreement had intended to rehabilitate and improve Sriwijaya Air's financial and operational performance and efficiency after significant losses the year prior.

[28][29] The agreement between the two parties had also reportedly revolved around Sriwijaya Air's inability to fulfil obligations to pay its debt to GMF Aero Asia, Garuda Indonesia's aircraft maintenance subsidiary.

The reconciliation proved to be short-lived when the Cooperation Agreement (KSO) between Garuda Indonesia and Sriwijaya Air was ultimately terminated on November 8, 2019.

[32] Following the split, the Sriwijaya Air Group announced agreements new contractors for ground and maintenance services unrelated to Garuda Indonesia.

[33] In 2021, amid financial difficulties intensified by the COVID-19 pandemic and the crash of Flight 182 on January 9, the airline cut its workforce and offered its employees to resign.

[34] Following the cuts, the Indonesian Ministry of Labour opened an inquiry on the airline after it allegedly failed to pay severance payments to its former employees.

[35] In October 2022, the airline entered a temporary debt restructuring measure (PKPU) following a request from a creditor fulfilled by the Central Jakarta District Court.
