Flight time: Buenos Aires to Milan

Route details

Distance breakdown: Buenos Aires to Milan

The 11,202-km great-circle distance between Buenos Aires (-34.82°N, 58.54°W) and Milan (45.63°N, 8.73°E) spans 80.5° of latitude and 67.3° of longitude, trending primarily east. In miles, this is 6,961 mi or 6049 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 11,202-km long-haul route, aircraft spend the majority of the 12h 57m to 14h 30m 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 EZE, takeoff and initial climb, descent and approach at MXP, and taxi-in to the gate. EZE is a major international hub where taxi times of 15–25 minutes are common during peak periods. At MXP, arrival taxi and gate assignment can add 10–20 minutes, especially during busy arrival banks. Oceanic tracks between Buenos Aires and Milan 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: Milan → Buenos Aires

The return flight from Milan to Buenos Aires 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 (Buenos Aires to Milan if eastbound, otherwise Milan to Buenos Aires) 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

Transatlantic flight times between Buenos Aires and Milan show clear seasonal patterns driven by the jet stream. In winter (November–March), the jet stream is at its strongest, creating the largest difference between eastbound and westbound times — sometimes exceeding 1 hour. In summer, the jet stream weakens and shifts north, resulting in more symmetrical flight times but potentially more turbulence-related routing deviations. Spring and autumn transitions are the most unpredictable, with the jet stream shifting rapidly. Weather-related delays are more common in winter at both EZE and MXP, which can add to actual gate-to-gate times beyond the cruise-phase effects.

Airport information

Ministro Pistarini International Airport (EZE) is a major international hub in Buenos Aires, Argentina. 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. Milan Malpensa Airport (MXP) is a major international hub in Milan, Italy. 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.
