Over the twelve months to August 2026, 76.6% of departures from London Heathrow to Minneapolis-St Paul International left within 15 minutes of their planned time, from 361 flights the UK Civil Aviation Authority matched to a schedule. That is within half a point of the 76.4% recorded across every UK departure to the United States, and it ranks 22nd of the 50 UK-to-US routes with a usable record. About one flight in four left at least 15 minutes behind schedule, and 5 of 366 scheduled departures, 1.4%, did not operate at all.
The route's 76.6% is a decline of 3 points from the same months a year earlier, when 79.3% 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
7.1% of departures left more than an hour late, and 0.27% 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 14.3 minutes, against 14.2 for all UK-to-US departures.
Carrier by carrier
Which airline leaves LHR for MSP on time
Delta Air Lines is the only carrier the DOT report shows on LHR to MSP, with 728 flights and an average of 218 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.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Delta Air Lines | 366 | 76.6% | 14 min | 1.37% | B |
Flights are scheduled departures in the CAA file, operated plus cancelled; on time is within 15 minutes of the planned off-block time. The DOT count below includes the return direction and may differ.

Across the year
When LHR to MSP runs late
August was the weakest month for departures at 61.3% on time and March the strongest at 93.5%, a swing of 32 points across the year. That is a wide seasonal range, wider than the gap between the best and worst carriers, so the month you fly matters more than the airline you pick. The DOT's count puts the busiest month at 62 flights in July 2025 and the thinnest at 56 in February 2026, so capacity follows the summer peak.

The DOT's international report counts flights in both directions together: 728 between LHR and MSP from July 2025 to June 2026, about one departure a day in each direction, carrying 159,027 passengers. That makes it the 23rd busiest of 31 US routes from London Heathrow and the 5th busiest of 8 European routes into MSP.
The return leg
MSP to LHR: arrivals back into London
Coming the other way, 79.0% of arrivals from Minneapolis-St Paul International into London Heathrow reached the gate within 15 minutes of schedule, across 363 flights. 34% 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. 1.09% of those arrivals were three hours or more late, the figure that decides a compensation claim on the return trip, and 0.8% were cancelled.

How London Heathrow is running
EUROCONTROL's figures for London Heathrow as a whole, every airline and every destination: 80.3% of departures and 80.5% of arrivals within 15 minutes of schedule from 1 January to 21 October 2026, with 96.7% of scheduled flights operated. The last seven days ran at 80.8% for departures, in line with the year. Air traffic flow management delay attributed to the airport averaged 1.2 minutes per arriving flight this year, 1.0 over the last week.

The arrival airport
Landing at Minneapolis-St Paul International
Minneapolis-St Paul International is scored on this site from the DOT's domestic data: 79.2% of its 114,673 domestic departures arrived on time over the last twelve months, with delayed flights running a little over an hour late, and 1.44% 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 MSP 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 MSP
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 Minneapolis-St Paul 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 MSP is covered only when the carrier is UK or EU based. The sector is about 4,003 miles, 6,441 km, which puts it in the top distance band.
