Hawaiian Airlines and Alaska Airlines now share space at San Francisco International Airport’s Harvey Milk Terminal 1, marking a new chapter as the two carriers work together to optimize operations and create a smooth travel experience for guests. 

The SFO relocation is the first of six that will include Sacramento, Ontario, Phoenix, Las Vegas and Los Angeles that will be completed by the end of 2025, according to a news release. The airlines’ systems will remain separate until a single passenger service system is put into place in 2026.

The second largest carrier at SFO and the largest domestic carrier at Harvey Milk Terminal 1, Alaska Airlines consolidated its operations this summer to provide an improved guest experience that includes advanced lobby technology and access to more gates.

Hawaiian has flown to the Bay Area since 1986 offering daily flights between SFO and Honolulu and Kahului on Maui aboard its Airbus A330 and A321neo aircraft.

Together, Hawaiian Airlines and Alaska Airlines will operate a total of four daily flights between SFO and Hawaii through December.
