Following the handover, Jin Air will conduct airworthiness inspections, amend its air operator's certificate, and perform test flights before placing the aircraft into revenue service. The A321-200 was originally due for Air Busan (BX, Busan), but was reportedly reassigned to Jin Air under the fleet plan for the group's future integrated low-cost carrier. The publication reported that Jin Air plans to take four factory-new A321neo series aircraft between September and December 2026. Overall, Jin Air operates an all-Boeing fleet of 33 aircraft, comprising seven B737-8s, nineteen B737-800s, three B737-900s, and four B777-200ERs. Korean Air (KE, Seoul Incheon) plans to combine Jin Air with Air Busan and Air Seoul (RS, Seoul Incheon) under the Jin Air brand as part of its integration with Asiana.
