WORKERS started digging the foundation yesterday of what is being billed as the world's largest satellite terminal building at the Pudong International Airport.

On completion, the new terminal will provide a faster transfer service and boost the punctuality rate of flights.

The H-shaped terminal — S1 and S2 — will be connected with terminals 1 and 2 through underground subways. It is expected to be completed by 2019, the Shanghai Airport Authority said.
