United Airlines is set to connect San Francisco to the South Australian city of Adelaide, with flights to take off from the Golden Gate city on Thursday, December 11. The route will operate seasonally three times a week.
The service to Adelaide will become United’s fourth Australian gateway from SFO, already offering non-stop flights to Brisbane, Sydney, and Melbourne year-round. This will be the first time a non-stop service has connected Adelaide to the United States, and it will be the only airline to provide non-stop services to four different ports in Australia.
Three Flights A Week
United will operate the seasonal service with its Boeing 787-9 Dreamliner, which will shuttle travelers nonstop from 
San Francisco International Airport (SFO) to Adelaide Airport (ADL), the largest city in the state of South Australia. The nearly 15-hour flight will provide passengers with the quickest route from the US to popular tourist hotspots such as Kangaroo Island, the Eyre Peninsula, and the Barossa Valley.
Departing from SFO on a Monday, Thursday, and Saturday, the flight will push back at 11:05 pm, arriving in Adelaide at 09:30 two days later (crossing the international date line). Return flights will leave Adelaide on Monday, Wednesday, and Saturday, pushing back at 2:55 pm local time, and arriving back in San Francisco the same day at 11:15 am.
The 787-9 will provide a total of 257 seats, including the popular United Polaris business class, Premium Plus premium economy cabins, alongside economy class. The South Australian airport celebrated the news back in April, when first announced, with the airport’s managing director, Brenton Cox, sharing below how important this route will be for ADL:
“Adelaide will now be connected directly to an entirely new continent – this is a core connection in our aviation network vision that has been decades in the making. This service will directly benefit business, investment, and our broader tourism economy.”
No More Stopovers En Route
Historically, those looking to travel to and from the United States to Adelaide have had to endure stopovers at other east-coast Australian airports such as Brisbane, Melbourne, and Sydney; however, from Thursday, travelers will be able to enjoy the new non-stop service until the end of March 2026. This means travelers can now fly from destinations such as Chicago, Washington, Denver, and Seattle to Adelaide with just one stop.
It is expected to see demand for the route from both sides of the Pacific, with Adelaide travelers being able to make the most of not only visiting the San Francisco Bay area, but also connecting into the airline’s wider domestic and international network from SFO.
The route to Adelaide will mark the airline’s sixth route to Oceania, complementing its existing Australian routes, including year-round services from Melbourne to San Francisco and Los Angeles, year-round flights from Sydney to San Francisco and Los Angeles, with seasonal services to Houston. Additionally, across the Tasman, United offers year-round flights to 
Auckland Airport, with seasonal services added to Christchurch Airport through the Southern Hemisphere summer season.
In addition, United Airlines announced daily flights to Bangkok and Ho Chi Minh City, both served via Hong Kong.
International Offering From Adelaide Airport
Adelaide is home to approximately 1.4 million inhabitants, the vast majority of South Australia’s 1.8 million residents. The airport, which is located just four miles (six kilometers) from the city’s CBD, served more than 8.7 million passengers in 2025.
While the airport has lacked a non-stop connection to the United States, it has an extensive international offering to most major Asian and Middle Eastern airports. International operators at the airport include:
