PEMCO World Air Services has announced the redelivery of a Boeing 737-300 freighter aircraft to China-based SF Airlines, the air cargo division of SF Express.

The freighter, converted by PEMCO’s partner STAECO in Jinan Shandong, China, marks the fourteenth redelivery of a B737-300/400 to SF Airlines since 2013.

SF Airlines plans to add five more PEMCO converted aircraft to its cargo fleet this year.

SF Airlines is a leading courier in China providing delivery service to over 15 countries, including the US.

PEMCO and STAECO have partnered on more than 50 Boeing 737-300 and -400 freighter modification projects since 2006.

PEMCO’s latest 737-300 freighter conversion for SF Airlines provides nine pallet positions, up to 43,100 pounds of payload, and 4,600 cubic feet of total volume.
