Over the twelve months to August 2026, 73.8% of departures from London Gatwick to Melbourne Orlando International left within 15 minutes of their planned time, from 61 flights the UK Civil Aviation Authority matched to a schedule. That is 3 points behind the 76.4% recorded across every UK departure to the United States, and it ranks 29th of the 50 UK-to-US routes with a usable record. About one flight in four left at least 15 minutes behind schedule, and 0 of 61 scheduled departures, 0.0%, did not operate at all.

The route's 73.8% is an improvement of 10 points on the same months a year earlier, when 63.7% 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

4.9% 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 15.2 minutes, against 14.2 for all UK-to-US departures.

Carrier by carrier

Which airline leaves LGW for MLB on time

TUI Airways is the only carrier the DOT report shows on LGW to MLB, with 113 flights and an average of 224 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 LGW to MLB runs late

The DOT's international report puts 18 flights on the pair in July 2025, the busiest month of the window, and 0 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.

The arrival airport

Landing at Melbourne Orlando International

Melbourne Orlando International is scored on this site from the DOT's domestic data: 84.0% of its 2,871 domestic departures arrived on time over the last twelve months, and 2.06% 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 MLB reaches a flight from LGW just as surely. The airport flies too little domestic traffic for a page of its own here.
