Follow CZ303 in real time

The aircraft appears below whenever it is airborne and inside receiver coverage. Its planned route is drawn between the two airports.

CZ303 is not transmitting right now. It may be between rotations, on the ground, or out of receiver range - Check back near 09:30 at CAN. The full map has the rest of the sky, and what is flying over me will name whatever is above you instead.

CZ303 at a glance

  • The trip: 7,529 km (4,678 miles) from Guangzhou to Sydney, flying south-east.
  • How long: 9h 15m gate to gate. That is about 814 km/h on average, taxi time included.
  • Your watch: set it 3 hours forward on arrival.
  • Window seat tip: the right (south-facing) side gets the sun on a daytime flight.
  • The plane: usually an Airbus A350-900. This route uses about 50% of how far it can fly.
  • When it goes: out of CAN in mid-morning, into SYD in late evening.

CZ303 route overview: CAN to SYD

CZ303 distance and great-circle path

CZ303 covers 7,529 km, or 4,678 miles. That makes it a long-haul flight, a widebody route with a full night's flying time. Of the 439 routes we track, it ranks 150 by distance.

The plane leaves Guangzhou heading south-east. On the map above, the line looks curved. That is normal. The shortest path over a round planet never looks straight on a flat screen. Our guide explains how the CAN-SYD route appears on a tracker map.

Why CZ303 block time differs from cruise time

The schedule allows 9.2 hours from gate to gate. That works out to about 814 km/h. An Airbus A350-900 cruises faster than that. The gap is taxi time, climbing, descending and holding.

Winds aloft shift the real flight time by up to an hour in either direction. See how high-altitude winds behave in our guide to turbulence and jet streams.

Can the Airbus A350-900 comfortably fly CZ303?

Not at all. At roughly 50% of its range, this is an easy trip for an Airbus A350-900. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Airbus A350-900.

What to know about CZ303

  • Time change: you land 3 hours ahead of the time you left.
  • Crosses the equator: you swap seasons between takeoff and landing.

CZ303 activity in the past 7 days

Our database contains 8 observations of CZ303 across 8 UTC dates in this window, most recently 2026-10-29. Those records contain 8 distinct transponder addresses.

The median recorded visibility was 440 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does CZ303 emit?

Worked from the great-circle distance and the fuel burn measured for Airbus A350-900, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown7,529 km
AircraftAirbus A350-900
Fuel burn rate6.03 kg per km
Fuel burned45,400 kg
CO2, whole flight143.5 tonnes
Seats, typical layout300
Passengers carried249 at an 83% load factor
CO2 per passenger576 kg

Where that lands by cabin

The aircraft burns the same fuel whoever is aboard, so the cabins divide one total rather than each carrying their own. A seat's share is the floor it takes up, which is why an economy seat comes out below the 576 kg cabin average and a flat bed well above it.

Economy246 seats, 204 flown
423 kg CO2 per seat
Business45 seats, 37 flown
1,226 kg CO2 per seat
First9 seats, 7 flown
1,691 kg CO2 per seat

Taken whole, CZ303 emits what 2,391 trees take back out of the air in a year. One economy seat on it accounts for about the same carbon dioxide as driving a petrol car 3,389 km, or 16,462 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at sectors of 9,208 km, 10,249 km and 12,116 km, all longer than this route, so the closest is held flat and the real figure is likely a little higher. It counts carbon dioxide only, and the cabin split assumes the layout typical of this size of aircraft. Read the full method, sources and caveats, or put CZ303 against another flight.

The route and typical schedule are maintained reference data. Live ADS-B observations are evidence of receiver coverage, not proof of on-time performance. Always confirm the operating date and times with the airline.
