As of September 2025, Trigana Air uses two passenger B737 in Papua for flights connecting Jayapura-Wamena and Jayapura-Dekai. One is this 1992 built -500, while the 2nd airframe is a -300 registered PK-YRA. PK-YSC has carried many registrations: initially as SE-DNK with Linjeflyg (lsd to LOT), then sold to SAS (still as SE-DNK). Next stops were with British Midland, bmi Baby and TAG Aviation (UK) as G-BVKD before it became N457US with Aero North International. Kalstar Aviation did import it to Indonesia as PK-KSP in July 2013. Next operator was Expressair as PK-TZD and now finally Trigana Air.
