History of Alaska Airlines’ presence at Sky Harbor
Alaska Airlines has served Phoenix Sky Harbor since the mid-1980s, when the airline expanded its route network beyond its home base in the Pacific Northwest into the Southwest. Over the following decades, Alaska steadily added destinations and increased flight frequency out of Phoenix as the airport grew into one of the busiest in the country.
A major turning point came with Alaska’s 2016 merger with Virgin America, which strengthened the airline’s presence in California and across the Southwest. New routes from Phoenix followed, reinforcing Alaska’s position in the region and giving travelers more nonstop options and competitive fares.
Where is Alaska Airlines at Sky Harbor?
Alaska Airlines operates from Terminal 3, officially named the John S. McCain III Terminal, at Phoenix Sky Harbor International Airport. Terminal 3 has 27 gates and also hosts Delta Air Lines, United Airlines, JetBlue, Spirit Airlines, and Hawaiian Airlines. Sky Harbor’s other active terminal, Terminal 4 (the Barry M. Goldwater Terminal), handles American Airlines and Southwest Airlines. Terminal 2 was permanently closed in 2020, so travelers today only need to worry about choosing between Terminal 3 and Terminal 4.
