Flight time: Melbourne to Los Angeles

Route details

Distance breakdown: Melbourne to Los Angeles

The 12,758-km great-circle distance between Melbourne (-37.67°N, 144.84°E) and Los Angeles (33.94°N, 118.41°W) spans 71.6° of latitude and 263.3° of longitude, trending primarily west. In miles, this is 7,927 mi or 6889 nautical miles. The great-circle path — the shortest distance over Earth's curved surface — is calculated using the Haversine formula from the two airports' precise coordinates.

Cruise speed and flight phases

On this 12,758-km long-haul route, aircraft spend the majority of the 14h 41m to 16h 24m journey at optimal cruise altitude of 35,000–42,000 feet, where modern wide-body jets achieve true airspeeds of 820–900 km/h (Mach 0.82–0.86). The initial climb and final descent represent a smaller fraction of total flight time compared to shorter routes. Aircraft like the Boeing 777, 787, or Airbus A350 typically operate routes of this distance, with step climbs during the flight to reach progressively more efficient altitudes as fuel burns off and the aircraft lightens.

Ground time and routing overhead

Our 30–50 minutes overhead allowance covers: taxi-out at MEL, takeoff and initial climb, descent and approach at LAX, and taxi-in to the gate. MEL is a major international hub where taxi times of 15–25 minutes are common during peak periods. At LAX, arrival taxi and gate assignment can add 10–20 minutes, especially during busy arrival banks. Oceanic tracks between Melbourne and Los Angeles follow organized route systems (like the North Atlantic Track system) that may add 5–10% to the theoretical great-circle distance. These tracks are assigned daily based on forecast winds.

Return flight: Los Angeles → Melbourne

The return flight from Los Angeles to Melbourne differs noticeably in duration due to upper-atmosphere wind patterns along this oceanic corridor. The jet stream — a high-altitude river of fast-moving air flowing generally from west to east — creates an asymmetry: the eastbound leg (Los Angeles to Melbourne if eastbound, otherwise Melbourne to Los Angeles) is typically 20–60 minutes shorter. Airlines adjust fuel loads and even routing to account for this, sometimes flying more southerly or northerly tracks on the headwind leg to minimize the impact. Over a year, the average time difference between the two directions on this specific route is estimated at 30–45 minutes.

Seasonal variation in flight times

Flight times between Melbourne and Los Angeles vary modestly by season — typically 10–20 minutes. Upper-level wind patterns shift with the seasons: winter generally brings stronger westerly winds at these latitudes, while summer patterns are more variable. Thunderstorm activity along the route corridor peaks in summer months, occasionally causing routing diversions that add distance. Winter operations may include de-icing delays at MEL, which extend the overall gate-to-gate time.

Airport information

Melbourne Tullamarine Airport (MEL) is a major international hub in Melbourne, Australia. As a tier-1 airport, it handles high traffic volumes, which means longer average taxi times but also higher flight frequency and competition that can benefit travelers on pricing. Los Angeles International Airport (LAX) is a major international hub in Los Angeles, United States. As a tier-1 airport, it handles high traffic volumes, which means longer average taxi times but also higher flight frequency and competition that can benefit travelers on pricing.
