SF Airlines: Inside the Cargo Fleet That Moves Chinese E-Commerce

History and positioning

Unlike almost all the other airlines on this list, SF Airlines was explicitly born as an all-cargo carrier, not as an offshoot of a passenger airline that added freight transport later. Its reason for being is logistics: guaranteeing the SF Express network fast delivery times on a national and international scale.

The fleet

The fleet has reached about 90 cargo aircraft, with a composition that reflects different loading needs: 17 Boeing 737 freighters for lighter regional links, 39 Boeing 757 freighters as the backbone of the network, 20 Boeing 767 freighters for larger volumes and 4 Boeing 747 freighters for the heaviest loads on the longest routes.

Routes and network

SF Airlines connects more than 110 cities worldwide, with a network designed around delivery times rather than the convenience of a passenger: flight schedules follow the logic of the SF Express sorting hubs, often with overnight departures to guarantee next-day delivery.

This is not a carrier you can book as a passenger, so the "ideal profile" discussion doesn't apply in the classic sense: the information is useful mainly to those who follow air traffic around Chinese airports or work in logistics and want to understand how their parcels travel. If you are following an SF Express shipment, the practical tip is to track it with the courier's tracking number rather than looking for a flight to book: SF Airlines operates exclusively on behalf of the logistics network and does not sell tickets to the public.
