First United Airlines flight to Adelaide takes off
By Andrew Curran.
The inaugural United Airlines flight to Adelaide (ADL) has departed San Francisco (SFO). The service, the first ever scheduled passenger flight between North America and the South Australian capital, left SFO just before midnight on December 11, 2025 (US West Coast time), and is due to land in Adelaide mid-morning on December 13.
United will become the only airline with nonstop service to four Australian cities — Sydney (SYD), Melbourne (MEL), Brisbane (BNE), and Adelaide. The US carrier has more routes, frequencies, and seat capacity on the US – Australia country pair than any other airline, including Qantas.
United Airlines will deploy a 257-passenger B787-9 on the Adelaide run. The westbound flight will take just shy of 16 hours to complete, while the run back to San Francisco is scheduled to take just under 15 hours.
Cards finally fall in Adelaide's favour
According to the South Australian State Government, which alongside Adelaide Airport, pitched in to incentivise United to trial the flights, over 44,000 US tourists visited South Australia in 2024, tipping AUD77 million (USD51.3 million) into the local economy.
However, South Australian Premier Peter Malinauskas said that for many years, the ambition of a direct route between South Australia and the US had been out of reach.
There are ample one-stop connections between Adelaide and the United States – Qantas via Sydney (SYD) or Melbourne (MEL); Air New Zealand via Auckland (AKL); Fiji Airways via Nadi (NAN); Singapore Airlines via Singapore (SIN); Cathay Pacific via Hong Kong (HKG); Emirates via (Dubai); and Qatar Airways via Doha (DOH). But until now, no Australian or US carrier has seen commercial value in non-stop flights from Adelaide to the US.
What’s changed? The incentives offered to United Airlines remain commercial in confidence, but those, alongside United’s longstanding willingness to experiment with international routes, its surplus aircraft during the Northern Hemisphere low season, and access to a city of 1.5 million people with no non-stop flights to the US, may have tilted the argument in Adelaide’s favour.
Will United's Adelaide flights work?
United’s juiciest market for its Adelaide service isn’t the relative handful of US tourists who make it to South Australia. Rather it’s South Australians sick of having to transit to travel to the US.
But the route’s success isn’t a slam dunk.
Is Adelaide a big enough city to sustain three San Francisco round-trips per week? Can United persuade South Australia’s many rusted-on Qantas loyalists that their product is as good or better than Qantas? And can United sell the many charms of Australia’s most under-rated state to its home market in the United States?
Further, while there are plenty of United flights feeding in and out of San Francisco, only Perth (PER) stacks up as a feeder city for the San Francisco-bound services. Local code share partner Virgin Australia has a daily flight from Perth that lands in Adelaide around two hours before the United flight departs. However, Virgin’s Perth-bound flight departs just 40 minutes after the United service lands in Adelaide – making for a very tight connection. Miss that and it’s about five hours until the next Perth flight on Virgin.
Nonetheless, between Adelaide and Perth, United Airlines is looking at a population catchment of over 3.5 million people.
In any case, United has already indicated that it will return to Adelaide next summer, having recently filed schedules saying it plans to operate the thrice-weekly B787-9 round-trips from December 3, 2026.
UA207 is due to land in Adelaide at 09.30am on Saturday, December 13.
