Delta Air Lines' list of foreign destinations from Sea-Tac Airport grew by one this week with the inaugural flight to Seoul from Seattle.
Delta already flew to Amsterdam, London, Paris, Beijing, Shanghai and Tokyo's two airports, Narita and Haneda, from Sea-Tac before it began service to Seoul Monday.
The Atlanta-based airline plans to add yet another Asian destination from Seattle this summer, Hong Kong.
Delta will offer more international seats than all other carriers combined from Seattle by the time the Hong Kong flight debuts.
On the Seoul route Delta will face two Korean carriers flying non-stop from Sea-Tac, Korean Airlines and Asian Airlines.
Delta is building Sea-Tac into its West Coast international hub. The airline is also adding its own flights to domestic destinations from Sea-Tac. The airline now offers 76 peak day flights from Sea-Tac. That number will grow to 86 by the end of summer.
The Seoul route will be served by a twin-engine Boeing 767-300ER. The plane will carry 210 passengers.
