Flight time: Montevideo to Newark

Route details

Distance breakdown: Montevideo to Newark

The 8,601-km great-circle distance between Montevideo (-34.84°N, 56.03°W) and Newark (40.69°N, 74.17°W) spans 75.5° of latitude and 18.1° of longitude, trending primarily west. In miles, this is 5,344 mi or 4645 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 8,601-km long-haul route, aircraft spend the majority of the 10h 03m to 11h 19m 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 MVD, takeoff and initial climb, descent and approach at EWR, and taxi-in to the gate. Taxi times at MVD are typically 5–15 minutes depending on traffic. At EWR, arrival taxi and gate assignment can add 10–20 minutes, especially during busy arrival banks. Continental air traffic corridors between Montevideo and Newark may add 3–8% beyond the great-circle distance. Standard instrument departures and arrivals at both airports use predefined routing that adds distance but ensures safe separation.

Return flight: Newark → Montevideo

The return flight from Newark to Montevideo is generally similar in duration to the outbound — typically within 10–20 minutes. Continental routes like this one are less affected by the jet stream asymmetry that makes oceanic east-west routes so uneven. The main variables affecting any difference are: prevailing winds at these latitudes (modest effect), different standard instrument departures/arrivals at each airport (minor effect), and air traffic congestion patterns that vary by time of day and direction.

Seasonal variation in flight times

Flight times between Montevideo and Newark 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 MVD and EWR, which extend the overall gate-to-gate time.

Airport information

Carrasco International Airport (MVD) is a regional airport serving Montevideo, Uruguay. Lower traffic volumes typically mean shorter taxi times and faster boarding, though flight frequency may be limited. Newark Liberty International Airport (EWR) is a major international hub in Newark, 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.
