BA15 at a glance

  • The trip: 6,294 km (3,911 miles) from Singapore to Sydney, flying south-east.
  • How long: 23h 40m gate to gate. That is about 266 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 a Boeing 777-300ER. This route uses about 46% of how far it can fly.
  • When it goes: out of SIN in late evening, into SYD in early morning. It is an overnight, so most of the cabin will try to sleep.

BA15 route overview: SIN to SYD

BA15 distance and great-circle path

BA15 covers 6,294 km, or 3,911 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 183 by distance.

The plane leaves Singapore 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 SIN-SYD route appears on a tracker map.

Why BA15 block time differs from cruise time

The schedule allows 23.7 hours from gate to gate. That works out to about 266 km/h. A Boeing 777-300ER cruises faster than that. The gap is taxi time, climbing, descending and holding.

Flying east, this route usually picks up tailwinds high up. The flight back west normally takes longer, even though the distance is identical. See how timing changes the trip in our red-eye flight guide.

Can the Boeing 777-300ER comfortably fly BA15?

Not at all. At roughly 46% of its range, this is an easy trip for a Boeing 777-300ER. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Boeing 777-300ER.

What to know about BA15

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

BA15 activity in the past 7 days

Our database contains 8 observations of BA15 across 8 UTC dates in this window, most recently 2026-10-29. Those records contain 7 distinct transponder addresses. The most frequently resolved route was SIN-SYD (8 records).

The median recorded visibility was 1437 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does BA15 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 777-300ER, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown6,294 km
AircraftBoeing 777-300ER
Fuel burn rate8.86 kg per km
Fuel burned55,759 kg
CO2, whole flight176.2 tonnes
Seats, typical layout365
Passengers carried303 at an 83% load factor
CO2 per passenger582 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 582 kg cabin average and a flat bed well above it.

Economy299 seats, 248 flown
422 kg CO2 per seat
Business55 seats, 46 flown
1,224 kg CO2 per seat
First11 seats, 9 flown
1,689 kg CO2 per seat

Taken whole, BA15 emits what 2,937 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 3,421 km, or 16,615 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 10,199 km, 11,112 km and 13,334 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 BA15 against another flight.
