Flight Deals from Denver to Sydney from $837

Denver to Sydney is about 8,350 miles. There is no scheduled nonstop service on this route, so the journey requires a connection.

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.

There are no non-stop flights from Denver to Sydney. The shortest connecting routing is United Airlines via Los Angeles, with a 2h 32m first leg, a 1h 33m layover, and a 15h 10m second leg for a total of 19h 15m. United also connects via San Francisco, and Qantas offers a one-stop option through Los Angeles.

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.

The Airport Link train is the fastest and most-used way into Sydney's city center, taking about 13–15 minutes from either terminal to Central Station, with trains running roughly every 10 minutes; a one-way adult trip costs about $18.70 including the station access fee. Taxis and rideshares like Uber or DiDi take around 20–25 minutes and typically cost $45–$65 one-way, with fixed taxi fares to the CBD from late 2025 set at $60 for a standard taxi. Public buses such as the 420 do not go directly to the CBD but connect to Mascot or Rockdale stations where you can transfer to a train, avoiding the airport station access fee for a much cheaper overall fare. Car rental desks from Avis, Hertz, and Budget are available in the arrivals areas, and private shuttle buses like Redy2Go offer prebooked shared rides to the city and suburbs. For most solo travelers the train is the clear default, while groups of two or more often find taxis or rideshares comparable in price and more convenient.

Average fares from Denver to Sydney bottom out around $426 in late January, making that the cheapest stretch to fly. The cheapest months overall are September at $440, January at $441, and October at $448. The most expensive period is late December, when average fares climb to about $574.

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.

Overnight red-eye flights are available from Denver to Sydney, though all require a connection since there is no nonstop red-eye. The overnight long leg departs Los Angeles around 10:30–10:50 PM or San Francisco around 11:05 PM, arriving in Sydney the next morning between 7:30 and 8:05 AM, operated by United, Qantas, or American. These connect through LAX or SFO after a short hop from Denver.

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.

There is no nonstop service from Denver to Sydney. The common one-stop routings connect through Los Angeles or San Francisco, with United Airlines typically operating via LAX or SFO, and Qantas Airways and American Airlines also connecting through LAX. United has around 4 daily connections via each of LAX and SFO, while Qantas and American each appear less frequently. A routing via Istanbul on Turkish Airlines is also possible but much longer.

Sydney has only one commercial airport, Sydney Kingsford Smith Airport. It is about 8 km south of the city centre and serves all international and domestic flights for the region.

Getting to Denver International Airport from downtown is easy, with several solid options. The RTD A Line train is the most popular choice for budget travelers, running every 15 minutes, 24/7, and reaching Union Station in about 37 minutes for just $10 each way. Ride-share services like Uber and Lyft, along with taxis, are the fastest door-to-door options at roughly 25–35 minutes and are great for convenience, though they cost significantly more than the train. Shared-ride shuttles and hotel shuttles offer a middle ground for door-to-door service, and if you drive yourself, both garage and economy parking are available on-site, with additional parking at several rail stations.

There is no nonstop service from Denver to Sydney. United Airlines operates the most connecting flights, using Boeing 787-9 aircraft on the long-haul legs via Los Angeles and San Francisco. Qantas flies connecting itineraries with Airbus A380-800 and Airbus A380 aircraft via Los Angeles, while American Airlines uses Boeing 777-300ER aircraft on its connecting service through Los Angeles and Turkish Airlines offers a connection via Istanbul on Airbus A350-900 aircraft.

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.

There is no nonstop service from Denver to Sydney, so the route is flown one-stop via Los Angeles, San Francisco, or Istanbul.

No major carrier on this route is unaligned.
