How often are these flights late or cancelled?
Denmark
In the twelve months from July 2025 to June 2026, 21.5% of 11,072 movements arriving into the UK were disrupted — more than fifteen minutes late or cancelled at short notice.
Put the other way round, 78.5% of 11,072 movements met the fifteen-minute convention. These are historical observations, not a forecast.
Definitions, denominators and limits
Arrivals into UK reporting airports only unless labelled departures. Denominator: operated movements plus short-notice cancellations (M+C). A movement is not a scheduled flight. Unmatched records are data quality, not outcomes. Cells below twenty movements are suppressed; twenty to forty-nine are descriptive and not ranked.

The four numbers at a glance
21.5% of 11,072 movements were disrupted over July 2025 to June 2026.
Average delay covers delayed movements only. Its range reflects rounded source means and the unknown count of exactly punctual movements.

Definitions, denominators and limits
Arrivals into UK reporting airports only unless labelled departures. Denominator: operated movements plus short-notice cancellations (M+C). A movement is not a scheduled flight. Unmatched records are data quality, not outcomes. Cells below twenty movements are suppressed; twenty to forty-nine are descriptive and not ranked.
What did the big disruptions do here?
Each event is compared with the twelve preceding calendar months and the first later return to baseline.
A worse month is not proof the named event caused it. The open data carry no delay-cause field. Recovery is observed for at most eight subsequent months.

Which time of year has been hardest?
Highest median: Jul, 37.9% across 6 months. Lowest median: Nov, 17.4% across 6 months.
Even the same calendar month differs across years. This is a record, not a forecast; pandemic years are excluded from the summaries.
Each cell is one calendar month of one year; the number is the share of that month’s arrivals that were disrupted. Darker means worse. A blank cell means no published data, not zero.

Arrivals vs departures
21.5% of 11,072 movements arrivals were disrupted, against 23.3% of 11,072 movements departures.
The directions have separate denominators. A departure delay does not establish late arrival at the final destination; legal conditions differ by direction and carrier.

Movements past the three-hour mark
0.2% of 11,072 movements were more than three hours late over July 2025 to June 2026.
Cancellation is counted separately and is not a three-hour delay. Monthly counts cannot establish a passenger claim.
