The four numbers at a glance
24.5% of 1,471 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.

|---|---|---|---|
| 24.5% of 1,471 movements | 3.3% of 1,471 movements | 23.7–62.0 minutes; delayed denominator 311–755 | 0.3% of 1,471 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.

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.
| Event | Direction | Disruption that month | Baseline before | Return to baseline |

Which time of year has been hardest?
Highest median: Sep, 31.9% across 4 months. Lowest median: Feb, 14.0% 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.
