Competition is heating up on European destinations from Sea-Tac Airport.
Atlanta-based Delta Air Lines this week inaugurated non-stop service to London from the Emerald City. British Airways already flies that route with two daily flights during the peak summer season.
London is the third European city Delta serves non-stop from Sea-Tac. The airlines flies from Sea-Tac to Paris and twice daily during the summer from Sea-Tac to Amsterdam.
Delta had flown to London regularly from Sea-Tac several years ago, but abandoned that route during the recession.
Delta will fly the London route with a Boeing 767 twin jet seating 208 passengers. The airline will serve Heathrow Airport.
London is the latest addition to Delta's growing international route structure from Sea-Tac. The airline already flies from Sea-Tac to Beijing, Shanghai and Tokyo's two airports, Narita and Haneda, from Sea-Tac. It plans to begin non-stop flights from Sea-Tac to Seoul and Hong Kong later this year.
The airline, of course, flies to Amsterdam and Paris from Sea-Tac.
Delta has added dozens of flights from Sea-Tac to domestic cities to provide feed for those international flights.
Many of those flights compete with its local partner, Alaska Airlines. Alaska recently announced a double-miles promotion with British Airways.
