Those looking to redeem Cathay Pacific Asia Miles towards this booking can expect to pay between 88,000 and 115,000 for a one-way trip from HKG to SEA in Business Class. Remember that Cathay Pacific Asia Miles has announced “adjustments” to the flight award mileage requirements, effective on 1 May 2026 00:00 (HKT), so you are better off booking your flight awards before the devaluations take effect. HKG-SEA one-way in Business Class will be priced at 91,000 miles on the lower end starting May 1st.

Takeaway

The new Cathay Pacific route to SEA is now operating on the A350-900. Members interested in flying the flagship Aria business-class cabin (on Boeing 777-300 ER) will have to continue to patronize select YVR routes, as it remains the only North American destination served with the Aria suites. The airline’s first dedicated lounge in New York, spanning nearly 10,000 square feet, will open in 2026 when Cathay Pacific relocates to the new Terminal 6 at JFK.
