No public record scores Madrid Barajas to Luis Munoz Marin International flight by flight. The US Department of Transportation's on-time database covers domestic flights only, and in Europe only the United Kingdom publishes punctuality by route, so what follows is built from the three measurements that do exist. The DOT's international report counts 1,067 flights between the two airports in the twelve months to June 2026, about one departure a day in each direction, flown by Iberia. EUROCONTROL's year-to-date figure has 67.6% of all departures from Madrid Barajas leaving within 15 minutes of schedule and 78.0% of arrivals landing within 15 minutes. At the other end, 77.7% of SJU's domestic departures arrived on time in the DOT data, which says something about how the airport itself runs, not about this route.
On EUROCONTROL's year-to-date arrival punctuality, Madrid Barajas ranks 14th of the 41 European airports on this site with service to the United States. Bilbao leads that table at 84.3% and Manchester closes it at 65.7%. A long-haul departure inherits the airport's morning: an aircraft that arrived late from its previous sector, or a departure queue built up by weather, delays the transatlantic wave with everything else.

US DOT, last twelve months of domestic departures
Without a route-level record, the useful question is what the two airports do to a schedule. EUROCONTROL attributes 0.4 minutes of air traffic flow management delay per arriving flight to Madrid Barajas so far this year; that is delay imposed by the network to hold traffic on the ground elsewhere, not the airline's own. In the DOT data, a delayed domestic departure from SJU ran a little over an hour late on average over the last twelve months, and 2.11% of its scheduled flights were cancelled.
Carrier by carrier
Who flies MAD to SJU
Iberia is the only carrier the DOT report shows on MAD to SJU, with 1,067 flights and an average of 212 passengers aboard each. A single-carrier route gives a delayed passenger no same-day alternative on the same ticket, which is worth knowing before booking a tight onward connection.

|---|---|---|---|---|
| Iberia | 1,067 | 100% | 89 | 212 |

Across the year
How often MAD to SJU flies through the year
The DOT's international report puts 115 flights on the pair in March 2026, the busiest month of the window, and 78 in September 2025, the thinnest. The schedule is close to flat through the year, which usually means business traffic rather than holiday demand underwrites it.

The arrival airport
Landing at Luis Munoz Marin International
Luis Munoz Marin International is scored on this site from the DOT's domestic data: 77.7% of its 35,332 domestic departures arrived on time over the last twelve months, with delayed flights running a little over an hour late, and 2.11% were cancelled. Those are domestic flights, not this route, but an arriving transatlantic flight shares the same runways, the same weather and the same ground delay programmes, so a bad day at SJU reaches a flight from MAD just as surely. The airport's own page has the hour-by-hour and month-by-month detail, and its live FAA status appears above when the FAA has something to say.

Your rights
EC 261/2004 on MAD to SJU
Every flight that departs Madrid Barajas falls under Regulation (EC) 261/2004, whichever airline flies it and wherever it lands. If it arrives at Luis Munoz Marin International three hours or more late, or is cancelled with under 14 days' notice, and the cause was within the airline's control, each passenger is owed €600 (€300 if the airline got you there under four hours late), on top of rebooking and care. Weather, air traffic control restrictions and strikes outside the airline are the usual exemptions. The return flight from SJU is covered only when the carrier is EU based. The sector is about 3,964 miles, 6,378 km, which puts it in the top distance band.

What to do with this
Booking MAD to SJU
There is no grade to give MAD to SJU without a route record, and this site does not invent one. What the three sources support: about one departure a day in each direction, a single carrier, a departure airport that gets 68% of its departures away on time and an arrival airport that runs 78% on time domestically. Leave two hours for any onward connection at SJU; immigration comes before the connecting flight.
Common questions
MAD to SJU questions
How often are MAD to SJU flights delayed?

Which airlines fly MAD to SJU?
Iberia. Iberia accounted for 100% of the 1,067 flights the DOT counted on the pair.
Can I claim compensation for a delayed MAD to SJU flight?
