Cathay Pacific Airways Ltd is in talks with shareholders on making another “substantial” order for new aircraft for the next decade, Chief Executive Officer Ronald Lam said.

The Hong Kong carrier will need more single-aisle jets, regional widebody aircraft and freighter planes as it cements its expansion needs from the start of the next decade, he said.

“We are working with our shareholders to make some decisions in the coming years,” Lam said Thursday at the Routes World 2025 conference in the city. “The order size I believe will be substantial because we are really committed to the development of Hong Kong and Hong Kong International Airport.”

Cathay’s biggest shareholders are Swire Pacific Ltd and Air China Ltd, who control roughly 75 percent of the airline as of its latest interim report.

Cathay has already pledged over HK$100 billion ($12.9 billion) worth of investments in the coming years, largely in new aircraft. The airline has a 10-year fleet plan spanning from 2026 to 2035, Lam said. The first five years of the plan is finalized, with the airline now focused on the next five. 

“We have committed to well over HK$100 billion dollars and we won’t stop there,” he added.

Cathay Group, which includes low-cost unit HK Express, has a fleet of roughly 230 aircraft, along with firm commitments and options for around 150 more.

In August, Cathay bought Boeing Co widebody planes for the first time in a dozen years — adding 14 of the company’s 777-9 aircraft to its fleet and taking its total commitment for ultra-long-haul planes to 35 jets.

Cathay’s fleet of long-distance planes also includes Airbus SE’s A350.
