Over the twelve months to August 2026, 62.3% of departures from London Heathrow to Cincinnati/Northern Kentucky International left within 15 minutes of their planned time, from 253 flights the UK Civil Aviation Authority matched to a schedule. That is 14 points behind the 76.4% recorded across every UK departure to the United States, and it ranks 48th of the 50 UK-to-US routes with a usable record. Roughly one flight in three left at least 15 minutes behind schedule, and 4 of 257 scheduled departures, 1.6%, did not operate at all.

The route's 62.3% is an improvement of 2 points on the same months a year earlier, when 60.4% left on time. Across every departure from the 25 UK airports the CAA reports, to any destination, 72.4% left within 15 minutes in the same period; transatlantic departures run slightly better than the UK average, partly because wide-body long-haul flights are scheduled with more slack than short-haul rotations. A single carrier accounts for almost every departure, so the route figure and the airline figure are the same number.

The UK261 compensation threshold

6.3% of departures left more than an hour late, and 0.40% left three hours or more behind schedule, roughly one flight in 100. Three hours at arrival is the threshold at which UK261 compensation becomes payable, £520 a passenger on a sector of this length; the CAA measures the departure, so a flight in that band left the gate three hours late, which is not quite the same test but rarely ends differently after seven hours over the Atlantic. The average delay across every matched departure, early ones counted as zero, was 19.3 minutes, against 14.2 for all UK-to-US departures.

Carrier by carrier

Which airline leaves LHR for CVG on time

British Airways is the only carrier the DOT report shows on LHR to CVG, with 490 flights and an average of 185 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.

Across the year

When LHR to CVG runs late

The DOT's international report puts 53 flights on the pair in May 2026, the busiest month of the window, and 29 in January 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.

The return leg

Coming the other way, 75.8% of arrivals from Cincinnati/Northern Kentucky International into London Heathrow reached the gate within 15 minutes of schedule, across 251 flights. 21% arrived more than 15 minutes early, which is normal for an eastbound crossing with the jet stream behind it and a schedule padded for the days it is not. 1.20% of those arrivals were three hours or more late, the figure that decides a compensation claim on the return trip, and 1.9% were cancelled.

The arrival airport

Landing at Cincinnati/Northern Kentucky International

Cincinnati/Northern Kentucky International is scored on this site from the DOT's domestic data: 79.2% of its 34,057 domestic departures arrived on time over the last twelve months, with delayed flights running a little over an hour late, and 1.98% 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 CVG reaches a flight from LHR 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

UK261 on LHR to CVG

Every flight that departs London Heathrow falls under UK261, the retained version of the EU regulation, whichever airline flies it and wherever it lands. If it arrives at Cincinnati/Northern Kentucky 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 £520 (£260 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 CVG is covered only when the carrier is UK or EU based. The sector is about 3,952 miles, 6,359 km, which puts it in the top distance band.
