China Southern Cargo is significantly expanding its intercontinental airfreight capacity with a long-term lease for three Boeing 777-300ER passenger-to-freighter conversions from AerCap, according to a FreightWaves report. The converted freighters will serve routes connecting the airline's Shanghai and Guangzhou hubs to destinations including Amsterdam, London Stansted, Frankfurt, Los Angeles, Chicago, and Hanoi and Ho Chi Minh City in Vietnam.
Lease agreement and delivery timeline
AerCap announced the lease on Wednesday, with the first converted 777-300 scheduled for delivery to China Southern Cargo in October 2027, according to an AerCap news release cited by FreightWaves. The second and third aircraft are slated for delivery in the first half of 2028. The aircraft will be converted by Israel Aerospace Industries (IAI), which developed the first 777 conversion program—dubbed the "Big Twin"—six years ago in partnership with AerCap. IAI has already delivered 11 777-300 converted freighters to customers, including Challenge Air Group, and has six more aircraft undergoing conversion, an IAI spokesperson told FreightWaves.
Fleet expansion and market context
This lease comes less than two weeks after China Southern Air Logistics ordered two classic 777 production freighters and five next-generation 777-8 cargo jets from Boeing as part of a fleet modernization program. The state-owned airline ranks in the top 10 carriers globally by cargo traffic, according to the International Air Transport Association. China Southern Cargo currently operates 12 self-owned Boeing 777-200 freighters and two Boeing 747-400 freighters, plus capacity from contract carriers and belly-hold space on passenger flights.
Last month, China Southern Cargo and FedEx Corp. agreed to explore cooperation on cargo logistics, further signaling its expansion ambitions.
Conversion program and aircraft specifications
The 777-300 converted freighter offers 110 tons of payload capacity and more than 28,600 cubic feet of volume, representing a 25% increase in cargo volume over the Boeing 777-200 production freighter. At 47 pallet positions, the converted aircraft accommodates 10 additional pallet positions compared to the 777-200, making it well-suited for less-dense cargo such as e-commerce goods, which now account for about 20% of global air cargo tonnage, according to FreightWaves.
The conversion process involves removing seats, adding large cargo doors, and extensive modifications to the fuselage, floor structure, loading systems, avionics, and other systems.
| Feature | Boeing 777-300ER Converted Freighter | Boeing 777-200 Freighter |
|---|---|---|
| Payload | 110 tons | Not specified in source |
| Cargo volume | 28,600 cu ft | 25% less than 777-300ER |
| Pallet positions | 47 | 37 (10 fewer) |
| Typical use | Less-dense cargo, e-commerce | General cargo |
Industry context and capacity demand
Widebody freighters are in high demand because cross-border trade continues to grow and a significant portion of the global freighter fleet is reaching retirement age, according to FreightWaves. The availability of converted 777-300 aircraft is increasing: Emirates took delivery of its first 777-300 passenger-to-freighter conversion last week, and IAI continues to deliver and convert aircraft. AerCap provides feedstock from its portfolio to IAI and markets the program to all-cargo airlines.
Implications for logistics operators
For freight forwarders and logistics managers, China Southern Cargo's expanded 777-300 freighter fleet will add intercontinental cargo lift on high-demand trade lanes, particularly between Asia and Europe and North America. The 25% greater volume per flight compared to the 777-200 means more capacity for e-commerce parcels and lightweight goods, which currently make up a significant share of airfreight. However, deliveries do not begin until late 2027, so near-term capacity remains unchanged. Operators should monitor the conversion program and China Southern Cargo's network adjustments as delivery dates approach.
