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.
