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 255 routes we track, it ranks 133 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.
