Boeing launched the Next-Generation 737-800 Boeing Converted Freighter (BCF) in February 2016 with orders and commitments for up to 55 conversions from seven customers. Through its freighter conversion program, Boeing transitions passenger airplanes into freighters, extending the economic life of the airplane. The 737-800 is the first Next-Generation 737 that Boeing has offered for conversion. While large freighters carry high-density cargo on long-range routes, the 737-800BCF will primarily be used to carry express cargo on domestic routes.

The 737-800BCF carries up to 52,800 pounds (23.9 metric tons) of cargo, flying routes of nearly 2,000 nautical miles (3,690 kilometers).

Existing passenger airplanes will be modified at select facilities located near conversion demand, including Boeing Shanghai. Modifications include installing a large main-deck cargo door, a cargo-handling system and accommodations for up to four non-flying crew members or passengers.
