- Book 2 to 5 months ahead for the best fares; long-haul seats sell out earliest for summer and holiday travel.
- Sydney is 17 hours ahead of San Francisco. Expect to lose 17 hours on the clock heading east, so an overnight or late-afternoon departure tends to arrive at a more usable hour.
Destination guide
Sydney: Harbor, surf beaches and 14 hours from LA
Sydney is the far end of the map for US travelers, but nonstops from Los Angeles, San Francisco, Dallas, Houston and New York make it a single long flight. The harbor, the Opera House, Bondi to Coogee and the Blue Mountains reward the journey.
Best time to visit: October–November and March–April (Southern Hemisphere spring and fall) are warm and less crowded. December–February is summer — beach season, school holidays and peak fares. June–August is mild and cheap.
