Chinese express cargo carrier SF Airlines last week added its 40th freighter aircraft to its fleet.
The freighter operator, which operates the largest all-cargo aircraft fleet in China, took delivery of the converted Boeing B757-200F aircraft at its Shenzhen Bao'an International airport base.
The aircraft is the first in the SF Airlines fleet to feature winglets, which offer "better takeoff performance and more economical fuel consumption", the carrier said.
SF Airlines' fleet now includes five B767s, 18 B757s and 17 B737s.
