In February 2016, Boeing launched a passenger-to-freighter conversion program, with converted aircraft designated as 737-800BCF (for Boeing Converted Freighter). Boeing started the program with orders for 55 conversions, with the first converted aircraft due for late 2017 delivery.[59] The first converted aircraft was delivered to West Atlantic in April 2018.[60]

At the 2018 Farnborough Airshow, GECAS announced an agreement for 20 firm orders and 15 option orders for the 737-800BCF, raising the commitment to 50 aircraft. Total orders and commitments include 80 aircraft to over half a dozen customers.[61] Since early 737NG aircraft become available on the market, they have been actively marketed to be converted to cargo planes via the Boeing Converted Freighter design because the operational economics are attractive due to the low operating costs and availability of certified pilots on a robust airframe.[citation needed]

Modifications to the 737-800 airframe include installing a large cargo door, a cargo handling system, and additional accommodations for non-flying crew or passengers.[61] The aircraft is designed to fly up to 1,995 nmi (3,695 km) at a MTOW of 174,100 lb (79,000 kg).
