How often are these flights late or cancelled?
Brussels Airlines
In the twelve months from July 2025 to June 2026, 30.4% of 2,069 movements arriving into the UK were disrupted — more than fifteen minutes late or cancelled at short notice.
Put the other way round, 69.6% of 2,069 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
30.4% of 2,069 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.

|---|---|---|---|
| 30.4% of 2,069 movements | 1.1% of 2,069 movements | 21.5–50.7 minutes; delayed denominator 607–1,334 | 0.2% of 2,069 movements |

Better or worse since the start of the archive?
Best month: Jun 2021, 6.8% of 73 movements. Worst month: Jul 2022, 56.7% of 180 movements.
The line traces every month. Lower disruption is better; gaps are never zeros. Pandemic readings describe a different operating regime.

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: Sep, 40.6% across 6 months. Lowest median: Feb, 16.5% across 7 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
30.4% of 2,069 movements arrivals were disrupted, against 46.1% of 2,074 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 2,069 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.
