Alaska Air to start route to New York’s JFK

Sea-Tac’s Alaska Airlines is taking on arch-rival Delta Air Lines on yet another route.

Delta and Alaska are locked in a battle for dominance at Sea-Tac. Delta recently announced several new flights to Alaska Airlines destination from Sea-Tac. It already flies many of the same routes as the local airline having bolstered its Sea-Tac schedule to support a gaggle of Delta international flights that depart from Sea-Tac. Alaska has the largest market share at Sea-Tac. Delta is second.
