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.

NAM Air (part of Sriwijaya Air) started as low-cost carrier in December 2013. At its peak, NAM Air operated eleven Boeing 737-500's, but is now down to just three at the time of upload. Since August 2025, mother company Sriwijaya Air offers direct flights from Makassar (Sulawesi) to Wamena (Papua), with a fuel stop in Timika on the way back. The new and revolutionary flight connection is contracted to NAM Air and 1994 built PK-NAS is seen here on one of it's first such flight. Initally flew for Continental and United as N19621, then as PK-CLO for Sriwijaya Air (between 2012 and 2016).
