The carrier currently operates only one Boeing 737F with registration PK-OTK (MSN 26288). The aircraft, which became Rimbun Air's first dedicated freighter in 2021, is previously operated by China Postal Airlines
The airline has acquired its second B737F registered B-2661 (MSN 26284) this year. The aircraft was ferried to Jakarta Soekarno-Hatta on January 20, 2022, but has yet to be deployed on the airline's routes in the coming weeks.
Rimbun Air aims to add a further three freighters by the end of this year and is in talks with several leasing companies, including B737-800 converted freighters.
Rimbun Air launched in 2018 as a regional STOL passenger charter operator. It also operates two DHC-6-400s to remote Indonesian destinations.
