Alaska Airlines is adding three more transcontinental nonstop destinations from its Sea-Tac Airport hub.
The airline announced Tuesday it will add flights to New Orleans and Tampa in June and to Detroit in September.
No airline now provides nonstop service between Sea-Tac and New Orleans and Sea-Tac and Tampa. Delta Air Lines offers nonstop flights from Seattle to its Detroit hub.
The Detroit flight is yet another invasion by Alaska into territory that had been exclusively Delta's from the Northwest. Alaska is also adding several flights from West Coast cities to Delta's Salt Lake City hub this year.
The new Alaska flights to the Delta hub airports were announced after Delta added multiple new flights in competition with Alaska from airports where Alaska had a dominant market share. Delta, for instance, is adding a flight between Sea-Tac and Anchorage, between Sea-Tac and Portland and from Seattle to San Diego, Los Angeles and San Francisco.
Delta hasn't been idle in adding to its Sea-Tac route map this week. The Atlanta-based airline announced new destinations from Seattle beginning next December including Palm Springs, Calif., Tucson, Phoenix and Jackson Hole, Wyoming. Alaska already flies to Palm Springs, Phoenix and Tucson.
Delta and Alaska remain code-sharing partners on many routes. On those routes the two airlines treat the other airline's flight as if it were their own when offering trips to consumers.
Delta began adding flights to its Pacific Northwest repertoire last year after it announced a bundle of new international flights from Sea-Tac. Those new destinations include London, Hong Kong and Seoul. Delta already offers flights from Sea-Tac to both of Tokyo's two airports, to Beijing, Shanghai, Amsterdam and Paris.
The new Alaska flights to New Orleans begin June 12, to Tampa on June 20 and to Detroit on Sept. 4. The airline is offering limited time introductory fares of $149 each way on the new flights.
Tampa is the third destination for Alaska in Florida where the airline already flies to Orlando and Fort Lauderdale from Sea-Tac.
