KEF→MCO

Icelandair is the only carrier the DOT report shows on KEF to MCO, with 531 flights and an average of 136 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.

The DOT's international report puts 57 flights on the pair in October 2025, the busiest month of the window, and 34 in September 2025, 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 Keflavík as a whole, every airline and every destination: 69.0% of departures and 77.8% of arrivals within 15 minutes of schedule from 1 January to 21 October 2026, with 88.5% of scheduled flights operated. The last seven days ran at 70.5% for departures, 2 points better than the year so far. Air traffic flow management delay attributed to the airport averaged 0.0 minutes per arriving flight this year, 0.0 over the last week.

Every US route from Keflavík, and its full punctuality record

Orlando International is scored on this site from the DOT's domestic data: 74.6% of its 159,940 domestic departures arrived on time over the last twelve months, with delayed flights running a little over an hour late, and 1.81% 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 MCO reaches a flight from KEF 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.

Orlando International (MCO) delay statistics, hour by hour and month by month

Every flight that departs Keflavík falls under Regulation (EC) 261/2004, whichever airline flies it and wherever it lands. If it arrives at Orlando 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 MCO is covered only when the carrier is EU based. The sector is about 3,529 miles, 5,678 km, which puts it in the top distance band.

There is no grade to give KEF to MCO without a route record, and this site does not invent one. What the three sources support: about five departures a week in each direction, a single carrier, a departure airport that gets 69% of its departures away on time and an arrival airport that runs 75% on time domestically. Leave two hours for any onward connection at MCO; immigration comes before the connecting flight.

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