MH122 route overview: KUL to SYD

MH122 distance and great-circle path

MH122 covers 6,584 km, or 4,091 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 175 by distance.

The plane leaves Kuala Lumpur 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 KUL-SYD route appears on a tracker map.

Why MH122 block time differs from cruise time

The schedule allows 8.2 hours from gate to gate. That works out to about 798 km/h. An Airbus A330-300 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 high-altitude winds behave in our guide to turbulence and jet streams.

Can the Airbus A330-300 comfortably fly MH122?

Not really. It uses about 56% of the Airbus A330-300's range. That leaves room for a full load of passengers and bags. The full numbers are on our aircraft page for the Airbus A330-300.

What to know about MH122

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

MH122 activity in the past 7 days

Our database contains 8 observations of MH122 across 8 UTC dates in this window, most recently 2026-10-29. Those records contain 7 distinct transponder addresses.

The median recorded visibility was 533 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does MH122 emit?

Worked from the great-circle distance and the fuel burn measured for Airbus A330-300, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown6,584 km
AircraftAirbus A330-300
Fuel burn rate6.37 kg per km
Fuel burned41,931 kg
CO2, whole flight132.5 tonnes
Seats, typical layout277
Passengers carried230 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.

Economy227 seats, 188 flown
417 kg CO2 per seat
Business42 seats, 35 flown
1,210 kg CO2 per seat
First8 seats, 7 flown
1,669 kg CO2 per seat

Taken whole, MH122 emits what 2,208 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 16,460 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 5,556 km and 10,275 km, interpolated to this route's 6,584 km. 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 MH122 against another flight.
