BCN→MIA

American Airlines flew 61% of the 1,171 flights between BCN and MIA in the DOT's count, with LEVEL on 271 and Iberia on 184. Loads averaged 238 passengers a flight, which on this route means wide-body aircraft nearly full.

The DOT's international report puts 131 flights on the pair in December 2025, the busiest month of the window, and 74 in February 2026, the thinnest. A summer-to-winter swing of that size means the winter schedule is a different operation: fewer frequencies, so a cancellation leaves a longer wait for the next seat.

EUROCONTROL's figures for Barcelona El Prat as a whole, every airline and every destination: 66.0% of departures and 76.6% of arrivals within 15 minutes of schedule from 1 January to 21 October 2026, with 95.6% of scheduled flights operated. The last seven days ran at 54.7% for departures, 11 points worse than the year so far. Air traffic flow management delay attributed to the airport averaged 1.9 minutes per arriving flight this year, 5.4 over the last week.

Every US route from Barcelona El Prat, and its full punctuality record

Miami International is scored on this site from the DOT's domestic data: 74.2% of its 111,132 domestic departures arrived on time over the last twelve months, with delayed flights running a little over an hour late, and 1.64% 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 MIA reaches a flight from BCN 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.

Miami International (MIA) delay statistics, hour by hour and month by month

Every flight that departs Barcelona El Prat falls under Regulation (EC) 261/2004, whichever airline flies it and wherever it lands. If it arrives at Miami 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 MIA is covered only when the carrier is EU based. The sector is about 4,688 miles, 7,543 km, which puts it in the top distance band.

There is no grade to give BCN to MIA 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 choice of three carriers, a departure airport that gets 66% of its departures away on time and an arrival airport that runs 74% on time domestically. Leave two hours for any onward connection at MIA; immigration comes before the connecting flight.

Spain publishes no route-level punctuality, so this page cannot grade the route. The UK pages in this section can, because the CAA does.
