Madrid to Buenos AiresLEMD → SAEZ
Adolfo Suárez Madrid–Barajas Airport (LEMD / MAD) in Madrid, Spain to Ezeiza International Airport - Ministro Pistarini (SAEZ / EZE) in Buenos Aires (Ezeiza), Argentina is 5,446 nautical miles — 10,086 kilometres, or 6,267 statute miles — on the great circle, on an initial bearing of 222°. A business jet at Mach 0.85 and FL410 takes about 11h 40m block time in still air.

Can the aeroplane make it?
Range here is usable range — book range at long-range cruise, less a reserve allowance. It is the figure that decides whether the leg closes, and it is the question most mappers do not answer.
Where the others would stop
For each type that cannot fly the 5,446 nm non-stop, the airport on or near the great circle that splits it into two legs that both clear, for the least extra distance. Types that would need more than one stop are marked.
| TYPE | BEST SINGLE STOP | LEGS | EXTRA |
|---|---|---|---|
| Challenger 350 | more than one stop | ||
| A320neo | Fernando de Noronha (SBFN), Brazil | 3,099 + 2,360 nm | 12 nm |
| A320 | Fernando de Noronha (SBFN), Brazil | 3,099 + 2,360 nm | 12 nm |
| B737 MAX 8 | Fernando de Noronha (SBFN), Brazil | 3,099 + 2,360 nm | 12 nm |
| B737-800 | more than one stop | ||
| An-124 | more than one stop | ||
| Concorde | Mossoró (SBMS), Brazil | 3,315 + 2,131 nm | 0 nm |
| King Air 200 | more than one stop | ||
| ATR 72 | more than one stop | ||
| Dash 8 Q400 | more than one stop | ||
Candidates are airports with a runway of 6,000 ft or more within 400 nm of the great circle, neither leg shorter than 15% of the whole, in still air. More in tech stops: where long flights stop and why.
Wind, month by month
The same business jet at Mach 0.85 and FL410, in each month’s average upper wind. LEMD to SAEZ is quickest in August (12h 00m) and slowest in May (12h 20m); SAEZ to LEMD is quickest in February (11h 10m) and slowest in July (11h 25m). The wind column is the average along-track component: plus is a tailwind.

| January | 12h 15m | −24 kt | 11h 15m | +21 kt |

Monthly means for 1991–2020 from NOAA’s NCEP/NCAR Reanalysis, at the pressure level nearest the cruise (about FL387), along the great circle. An average is smoother than any one day’s jet stream, so a given flight can see much more or much less; airlines also move the track to use the wind, which this does not. More in how wind changes block time.
How far from an airport?
The worst point on the great circle is 2h 03m from the nearest suitable airport, Espargos (GVAC), at the one-engine diversion speed Overfly uses (430 kt in still air). A twin flying this track needs ETOPS 180 approval or more: ETOPS 180 allows up to 180 minutes from an alternate.
| EQUAL-TIME POINT | BETWEEN | TO EACH |
|---|---|---|
| 4.5°N 31.4°W | Espargos (GVAC) and Maceió (SBMO) | 2h 03m |
A suitable airport here is one OurAirports classes as large with a runway of 8,000 ft or more. An operator’s real alternates also depend on weather, fire cover and approval, and its diversion speed on the type. More in equal-time points and ETOPS, explained.
The two fields
Questions people ask about this route
How far is it from Madrid (LEMD) to Buenos Aires (SAEZ)?
5,446 nautical miles. That is 10,086 kilometres or 6,267 statute miles, measured as a great circle between Adolfo Suárez Madrid–Barajas Airport and Ezeiza International Airport - Ministro Pistarini.
How long is the flight from Madrid to Buenos Aires?
About 11h 40m block time for a business jet cruising at Mach 0.85 at FL410 in still air, including 30 minutes of taxi, climb and descent. Wind moves that figure in either direction — eastbound across the North Atlantic or the Pacific it can be an hour or more. This page is deliberately still-air so the figure is stable and citable; to apply the month's average upper winds from NOAA, open the route in the mapper and switch on seasonal winds.
How much does wind change the flight time between Madrid and Buenos Aires?
In the average upper wind, Madrid to Buenos Aires at Mach 0.85 runs from 12h 00m in August to 12h 20m in May, and the return from 11h 10m in February to 11h 25m in July. Those are 1991–2020 monthly means from NOAA's reanalysis; on a given day the jet stream can make the difference larger or smaller.
What is the initial bearing from Madrid (LEMD) to Buenos Aires (SAEZ)?
222° true at the departure point. A great circle changes heading continuously, so this is the initial bearing, not a constant one.
Which aircraft can fly Madrid to Buenos Aires non-stop?
Of the types Overfly carries, G650ER, G550, Global 7500, Falcon 8X, Falcon 7X, A350-900, B777-300ER clear it on usable range — that is book range less a reserve allowance. Challenger 350, A320neo, A320, B737 MAX 8, B737-800, An-124, Concorde, King Air 200, ATR 72, Dash 8 Q400 would need a tech stop.
