Methodology: learn how we calculate these charts
The charts “When is the cheapest time to fly?”, “How far in advance should I book?”, “What's the cheapest day of the week to fly?” and “What do round-trip flights from Seattle to Sydney cost?” are built from the prices Priceline customers actually paid for flights on this route over the past 12 months or more.
Where a route has too few bookings to fill every point in a chart, we borrow the shape of the curve from a group of routes with similar price behavior and fit it to the fares booked on this route.
Because past fares don’t reflect today’s market, we then adjust the historical prices for current conditions such as inflation and fuel costs, using the round-trip fares found in recent searches on this route.
The chart “When is the best time of day to fly?” is calculated directly from the fares found in recent searches, not from historical bookings.
Frequently Asked Questions
Everything you need to know about flying from Seattle to Sydney.
What is the typical flight duration from Seattle to Sydney?
Seattle to Sydney is about 7,750 miles. The route requires a connection, as there is no scheduled nonstop service.
Methodology
Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.
Are there any direct flights from Seattle to Sydney?
There is no non-stop service from Seattle to Sydney — every routing connects. The shortest routing is on Alaska Airlines via Honolulu, at 17 hours 50 minutes total (6 hours 20 minutes to Honolulu, a 45-minute layover, then 10 hours 45 minutes onward). United offers the next-quickest options via San Francisco at 18 hours 30 minutes, and Qantas flies one-stop via Los Angeles from about 20 hours 53 minutes.
Methodology
Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.
What are the ground transportation options in Sydney?
Sydney Airport sits just 8–9 km from the CBD, and the fastest way into the city is the Airport Link train, which reaches Central Station in about 13–15 minutes with trains every 10 minutes; an adult one-way trip costs roughly $18.70 in station access fee plus a small rail fare. Taxis and rideshares such as Uber and DiDi are also available, with a typical taxi or rideshare fare of $45–$65 and a journey time of about 20 minutes, making them comparable to the train for two or more travelers. Public buses do not serve the CBD directly, but routes 350 and 420 connect to nearby train stations like Mascot for a cheaper, though slower, journey. Car rental desks from Avis, Hertz, and Budget are located in the arrivals areas of both international and domestic terminals. Most travelers heading to the city center use the Airport Link train for its speed and reliability.

When is the cheapest time to fly from Seattle to Sydney?
Fares from Seattle to Sydney are lowest in late January, around $1,013. September is the cheapest month overall, averaging $1,041, followed by January ($1,045) and October ($1,065). December is the most expensive month at about $1,279, and fares peak in late December at about $1,357. The yearly average is $1,135. Fares are adjusted to current market conditions.
Methodology
Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.
How far in advance should I book tickets from Seattle to Sydney?
Book about 5 weeks before departure for the best fares from Seattle to Sydney, around $987. Booking in the final days before the flight costs about $1,175, $188 more. Booking six months ahead runs about $1,506. Fares are adjusted to current market conditions.
Methodology
Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.
Are overnight (red‑eye) flights available from Seattle to Sydney?
There are no nonstop red-eye flights from Seattle to Sydney, but overnight connections are available. Most route through Los Angeles or San Francisco, with Qantas departing LAX around 21:25–22:30 and landing in Sydney at 06:25–07:30 the next morning, or United departing SFO at 23:05 and landing at 07:55.

Methodology
Red-eye flights are identified from scheduled local departure and arrival times and block times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes. A flight counts as a red-eye when it departs in the afternoon or evening (3 p.m. or later local time) or in the early hours before 4 a.m., and is in the air at some point between midnight and 4 a.m. local time at both its departure airport and its arrival airport. An evening flight that lands before midnight at its destination is never counted, nor is a morning departure or a daytime long-haul that reaches the next calendar date only because of time zones. Each red-eye is labelled with its timing (for example, overnight and landing the next morning, or late-night and landing after midnight). For connecting itineraries the same rule is applied to the longer leg, from one representative day's flight search.
Which airlines usually operate this route from Seattle to Sydney?
Seattle to Sydney has no nonstop service, so travelers connect through hubs like Honolulu, San Francisco, Los Angeles, Vancouver, Tokyo Haneda, or Hong Kong. Alaska Airlines offers the fastest one-stop routing via Honolulu at 17h 50m, while United Airlines connects through San Francisco or Los Angeles with frequent daily options. Qantas Airways and American Airlines also operate one-stop itineraries via Los Angeles, and All Nippon Airways, Cathay Pacific, and Hainan Airlines provide longer connections through their Asian hubs. Alaska Airlines, Qantas, American, and Cathay Pacific are oneworld members, while United, Air Canada, and All Nippon Airways belong to Star Alliance.
Methodology
Airlines and weekly frequencies come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.
Which airport should I use in Sydney?
Sydney has only one commercial airport, Sydney Kingsford Smith Airport (SYD), located about 8 km south of the city centre. It serves all major international and domestic flights, including Qantas, Virgin Australia, and many global carriers, making it the sole choice for this route.
How do I get to Seattle-Tacoma Intl Airport from the city center?
Getting to Seattle-Tacoma International Airport from downtown Seattle is easiest and most popular via the Link light rail, which reaches the airport in about 35–40 minutes for roughly $3 and runs every 8–10 minutes for most of the day, with a night bus covering early-morning gaps. Taxis and ride-shares like Uber and Lyft pick up on level 3 of the parking garage and offer a direct 20–30 minute trip at a significantly higher cost than rail, while shared shuttle services serve hotels and residences across the region. Driving yourself is possible via I-5, about 15 miles south of downtown, though parking at the airport or nearby garages is the most expensive option. For the fastest door-to-door trip, a taxi or ride-share wins when traffic is light, but the light rail remains the most economical and reliable choice for most travelers.

Methodology
Aircraft types come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.
