ORY→SFO

French Bee is the only carrier the DOT report shows on ORY to SFO, with 275 flights and an average of 351 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 54 flights on the pair in July 2025, the busiest month of the window, and 0 in June 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 Paris Orly as a whole, every airline and every destination: 70.4% of departures and 77.5% of arrivals within 15 minutes of schedule from 1 January to 21 October 2026, with 95.1% of scheduled flights operated. The last seven days ran at 55.6% for departures, 15 points worse than the year so far. Air traffic flow management delay attributed to the airport averaged 1.4 minutes per arriving flight this year, 5.8 over the last week.

Every US route from Paris Orly, and its full punctuality record

San Francisco International is scored on this site from the DOT's domestic data: 75.3% of its 148,532 domestic departures arrived on time over the last twelve months, with delayed flights running about an hour late, and 1.00% 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 SFO reaches a flight from ORY 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.

San Francisco International (SFO) delay statistics, hour by hour and month by month

Every flight that departs Paris Orly falls under Regulation (EC) 261/2004, whichever airline flies it and wherever it lands. If it arrives at San Francisco 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 SFO is covered only when the carrier is EU based. The sector is about 5,578 miles, 8,975 km, which puts it in the top distance band.

There is no grade to give ORY to SFO without a route record, and this site does not invent one. What the three sources support: about three departures a week in each direction, a single carrier, a departure airport that gets 70% of its departures away on time and an arrival airport that runs 75% on time domestically. Leave two hours for any onward connection at SFO; immigration comes before the connecting flight.

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