Cathay Pacific will open service between Hong Kong and Seattle in April 2026, returning to a route the carrier dropped at the beginning of the pandemic.
The airline previously flew between Hong Kong International Airport (HKG) and Seattle-Tacoma International Airport (SEA) from March 2019 to March 2020. The resumed route will be operated 5X-weekly with an Airbus A350-900 configured to carry 250 passengers, including 38 in business and 28 in premium economy.
Cathay will offer 2,500 two-way weekly seats on the route. When the carrier last flew between HKG and SEA—the week of March 22, 2020—it operated 1,680 two-way weekly seats, according to OAG Schedules Analyzer data. At its peak capacity on the HKG-SEA route in October 2019, Cathay offered 3,920 two-way weekly seats.

Delta Air Lines also operated the HKG-SEA route previously but dropped it in October 2018. No carrier currently operates on the route.
SEA will mark Cathay’s ninth destination in North America. The most recent addition was Dallas-Fort Worth International Airport (DFW), which the carrier started serving from HKG in April 2025. The HKG-DFW route, which is being operated with an A350-1000 aircraft, will ramp up from 4X-weekly service to daily flights from Oct. 26.
Both Cathay and SEA noted the Hong Kong-Seattle route will enable passengers to connect via HKG to points in Mainland China, Southeast Asia and India.
The HKG-SEA route will strengthen “business and cultural ties between Hong Kong and a dynamic tech hub in the U.S.,” Cathay Chief Commercial Officer Lavinia Lau said. “This route ... also supports the growing demand for connectivity between Asia and North America, particularly among travelers from the Chinese mainland and India.”
Aside from Dallas, other North American cities currently served by Cathay include Boston, Chicago O’Hare, Los Angeles, New York JFK, San Francisco, Toronto Pearson and Vancouver. The airline operates 110 weekly flights between HKG and North America.
