The route

The transpacific flight between San Francisco and Sydney is a flagship route for United Airlines, bridging the gap between the California tech corridor and Australia's largest city. This long-haul service is a vital link for international business, tourism, and diplomatic travel across the Pacific Ocean.

United Airlines operates a daily, year-round service between San Francisco International Airport and Sydney Kingsford Smith Airport. Utilizing the modern Boeing 787-9 Dreamliner, the flight offers a non-stop connection with a duration of approximately 15 hours, traversing thousands of miles of ocean.
