KAYAK’s top tips for finding a cheap flight from San Francisco to Sydney

  • Getting to San Francisco International Airport (SFO) is easy and convenient from anywhere in the Bay Area. There are plenty of public transportation options to choose from, including the Bay Area Rapid Transit (BART) rapid rail to travel from San Mateo County, the East Bay, or the city of San Francisco. Caltrain commuter rail and bus routes are also available to SFO from San Mateo County, San Francisco, and Palo Alto. Taxis and rideshares are easily accessible from the airport terminals.
  • Sydney Kingsford Smith Airport (SYD) is located about 8km from the Sydney city center and is about a 25min ride away. Public transportation is available through the Airport Link train and is about a 30min ride from SYD. Other options include rideshare cars and taxis, which will cost about AU$55 ($42.50) each way.
  • When traveling on any international flight, keep in mind that wait times at security, customs, and transit lines will be longer because of the larger number of travelers. U.S. travelers to SYD have the option to use the SmartGate to self-process through passport control and potentially save some time going through the immigration and customs line.
  • Business travelers will find that both SFO and SYD have much to offer to make your trip hassle-free. Several airline lounges, free Wi-Fi throughout the airports, business centers, and shower facilities are all easily accessible at both airports. In addition, there are multiple hotels in and around each airport to make your early morning or late-night connections easy.
  • Traveling with kids? SFO has a Kids'Spot, an interactive children's exploration and play area where kids can get their wiggles out before the long flight to Sydney. SFO also features extensive museum exhibits and self-guided tours. Sydney Airport has an interactive play area, but the highlight is the Kid's Cinema, where they can watch children's tv shows in a comfortable setting.

Terrible. Our first time back on United for 10 years, the seats in Polaris class are small and uncomfortable. They have squished too many people in to get more $$$. The staff are not friendly and not wanting to accommodate. I asked for two salads rather than a main meal and was advised no we wont do that. Then asked what I would like for breakfast and given something else anyway. I will not be flying United International anytime soon.

The flight crew where really good. Better then the crew from BNE to SFO

Food should be changed in menu Many muslims travels in this airlime they need to add one Halal meal

left on time, reasonable boarding process arrived early luggage came out quickly

Some flight attendants were great others were cranky. Seats were very tight and sitting on an aisle was very hard as the carts and people walking constantly bumped shoulder and arm.

Pushed back only to get deplaned due to a tire damaged by ground crew. They did at least go pretty fast. The bathrooms should be banned under the Geneva convention. No room to even sit straight on the toilet. The under-seat entertainment units block what little leg room there is.

United airlines has the best customer experience from booking to arrival. I always fly United airlines. The mileage program is excellent

from SFO-> FRA flight, AVML meal was significantly less compared to regular meal, especially no Desert, no Bread, no sides.

This was an older airplane. The cabin was constantly warm to hot throughout the 10 hour flight and there were no vents to personalize air flow. Also since it was an older plane, the material and comfort of the chairs were very uncomfortable. I left my flight with major soreness on my tailbone.

Older aircraft, no meal, only food was for purchase. Not impressed United.
