WAW→ORD

LOT Polish Airlines is the only carrier the DOT report shows on WAW to ORD, with 858 flights and an average of 230 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 105 flights on the pair in July 2025, the busiest month of the window, and 34 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 Warsaw Chopin as a whole, every airline and every destination: 72.9% of departures and 78.1% of arrivals within 15 minutes of schedule from 1 January to 21 October 2026, with 96.2% of scheduled flights operated. The last seven days ran at 62.8% for departures, 10 points worse than the year so far. Air traffic flow management delay attributed to the airport averaged 0.5 minutes per arriving flight this year, 2.7 over the last week.

Every US route from Warsaw Chopin, and its full punctuality record

Chicago O'Hare International is scored on this site from the DOT's domestic data: 70.8% of its 363,008 domestic departures arrived on time over the last twelve months, with delayed flights running a little over an hour late, and 2.80% 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 ORD reaches a flight from WAW 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.

Chicago O'Hare International (ORD) delay statistics, hour by hour and month by month

Every flight that departs Warsaw Chopin falls under Regulation (EC) 261/2004, whichever airline flies it and wherever it lands. If it arrives at Chicago O'Hare 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 ORD is covered only when the carrier is EU based. The sector is about 4,672 miles, 7,517 km, which puts it in the top distance band.

There is no grade to give WAW to ORD 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 73% of its departures away on time and an arrival airport that runs 71% on time domestically. Leave two hours for any onward connection at ORD; immigration comes before the connecting flight.

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