AerCap Cargo has signed lease agreements for three Boeing 777-300ERSF converted freighters with China Southern Air Logistics, marking the first major Chinese carrier to operate this high-capacity variant. The Dublin-based lessor will deliver the first aircraft in October 2027, with the remaining two arriving sequentially thereafter. These converted ‘Big Twin’ freighters offer 811 cubic meters of cargo volume and a 100-tonne payload, delivering 25% more capacity than production 777-F models. The deal stems from a joint conversion program launched by AerCap and Israel Aerospace Industries in 2019, utilizing aircraft originally delivered to Emirates as passenger jets in 2006. China Southern joins Emirates SkyCargo, which began commercial operations with the first unit on 30 June 2026, to strengthen long-haul freighter capabilities without waiting for new production freighters.
