The air charter operator has been transporting BHP Iron Ore employees to work and back in the Pilbara since 2009. The renewal includes a two-year extension option.
Under this contract Alliance will provide 14 services a week between Perth Airport and the Coondewanna and Barimunya airports, using a fleet of 13 jet aircraft.
Alliance managing director Scott McMillan said the company was delighted to be able to continue to supply air services to BHPIO for the next seven years.
"This extension is further evidence of Alliance's history of outstanding customer retention," he said.
"The commitment shown by all our staff in delivering safe and industry leading on time air charter services has once again played an important role in securing this extension."
