Over the twelve months to August 2026, 66.7% of departures from London Gatwick to Miami International left within 15 minutes of their planned time, from 15 flights the UK Civil Aviation Authority matched to a schedule. That is 10 points behind the 76.4% recorded across every UK departure to the United States. About one flight in three left at least 15 minutes behind schedule, and 0 of 15 scheduled departures, 0.0%, did not operate at all.

The route's 66.7% is a decline of 8 points from the same months a year earlier, when 75.1% 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

6.7% of departures left more than an hour late, and 0.00% left three hours or more behind schedule, almost no flights. 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 17.0 minutes, against 14.2 for all UK-to-US departures.

Which airline leaves LGW for MIA on time

Across the year

When LGW to MIA runs late

The DOT's international report puts 62 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.

The arrival airport

Landing at Miami International

Miami International is scored on this site from the DOT's domestic data: 74.2% of its 111,132 domestic departures arrived on time over the last twelve months, with delayed flights running a little over an hour late, and 1.64% 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 MIA reaches a flight from LGW 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 LGW to MIA

Every flight that departs London Gatwick falls under UK261, the retained version of the EU regulation, whichever airline flies it and wherever it lands. If it arrives at Miami 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 MIA is covered only when the carrier is UK or EU based. The sector is about 4,433 miles, 7,133 km, which puts it in the top distance band.
