How often are these flights late or cancelled?
STN ↔ MADRID
In the twelve months from July 2025 to June 2026, 33.7% of 1,400 movements arriving into STN were disrupted — that is, they landed more than fifteen minutes late or were cancelled at short notice.
Put the other way round, 66.3% of 1,400 movements arrived on time by the industry's fifteen-minute standard. Severe delays were rarer: about one arrival in every 200 crossed the three-hour mark. Lower is better on every figure on this page. These numbers describe what happened on the route; they are not a prediction for any individual flight.
Definitions, denominators and limits
- “Disrupted” means an arrival more than fifteen minutes late or a short-notice cancellation. The denominator is operated movements plus short-notice cancellations.
- Arrivals into the UK airport only; all published carriers.
- Crossing three hours is one condition for compensation, but monthly data cannot establish any individual passenger’s rights.
- Delay cause is not published in the open data.
- Source: CAA punctuality statistics · snapshot 17/08/2026 10:24 · method route-record-v2.1.
0 operations (0.00%) excluded because their published percentages could not be reconciled to whole numbers. Excluded operations enter neither the numerator nor the denominator. Outcome figures and comparisons are unavailable when the excluded share exceeds fifteen percent.
The four numbers at a glance
In the twelve months from July 2025 to June 2026, 33.7% of 1,400 movements were disrupted and no events in 1,400 movements were cancelled at short notice.
When a flight was late, it was typically late by the range shown below. The delay is given as a range, not a single number, because the regulator rounds its published percentages and never says how many flights landed exactly on time.
| Disruption share | Short-notice cancellations | Average delay among delayed flights only — bounds | Operations |
|---|---|---|---|
| 33.7% of 1,400 movements | no events in 1,400 movements | 34.1–60.2 min; N of delayed flights=472–791 | 1,400 |
Definitions, denominators and limits
The bounds account for CAA rounding and the unknown number of zero delays. A point average across all operated movements, including punctual ones, would answer a different question and is not used here.
When it is late, how late is it?
Most delays here are short. The ladder below shows how many arrivals crossed each threshold, from a quarter of an hour up to six hours; each rung can only be smaller than the one above it.
Cancellations are counted separately: no events in 1,400 movements. “One in N” means how many arrivals you would typically see between events at that level.
Delay ladder table: share, movements and one-in-N
| Delay | Share and n | Movements | One delay in every N operations |
|---|---|---|---|
| >15 min | 33.7% of 1,400 movements | 472 | 3.0 |
| >30 min | 21.4% of 1,400 movements | 300 | 4.7 |
| >60 min | 9.9% of 1,400 movements | 138 | 10.1 |
| >120 min | 2.4% of 1,400 movements | 33 | 42.4 |
| >180 min | 0.5% of 1,400 movements | 7 | 200.0 |
| >360 min | 0.1% of 1,400 movements | 2 | 700.0 |
Definitions, denominators and limits
CAA counts delays strictly greater than each threshold, so exactly three hours is inseparable from the previous bucket. The ladder describes the archive, not a forecast.
Slightly late, or occasionally a disaster?
When this route runs late, it is usually only a little late: big blow-ups are rarer here than on the typical UK route.
The histogram below counts every recorded arrival, from more than fifteen minutes early through to more than six hours late. A tall bar near the middle and a thin right-hand tail is the healthy shape.
Definitions, denominators and limits
Ratio of the long tail to sixteen-to-sixty-minute delays: 0.0210; corpus median 0.0217; 2056 routes in the corpus. The shape is compared conditionally among delays; the class name does not measure absolute frequency. Histogram counts and shares cover all recorded operations including unmatched records; reconstructed uniquely.
Has this route got better or worse since 2018?
Best month: Aug 2021, 4.8% of 84 movements. Worst month: Sep 2025, 73.3% of 86 movements.
The line traces every month in the archive; lower is better. Gaps are months with no published data, never zeros. The 2020 and 2021 readings reflect the pandemic, not normal service.

What did the big disruptions actually do here?
Each named event below is shown against this route’s own baseline for the twelve months before it, and against how long the route took to get back to that baseline.
A month worse than baseline is not proof the named event caused it: the open data carry no delay-cause field at all. Some events sit near the edge of the archive, which limits how long a recovery can be traced.
| Event | Direction | Disruption that month | Baseline before | Return to baseline |

| Pandemic regime · Jun 2020 | Arrivals | suppressed: fewer than twenty movements | no complete baseline | not enough data: needs a complete baseline and a publishable event month |

Definitions, denominators and limits
The baseline is the unweighted mean share over the twelve preceding calendar months. The return window is the following eight months, up to the end of the archive. Return means the first observed value at or below the baseline; it is not the duration of the disruption itself. If the event month is already below the baseline, counting still starts the month after. Gaps and suppressed cells are not treated as zeros or as recovery.
Which time of year has historically been hardest?
July has historically been the hardest month on this route: in a typical July, 50.0% of arrivals were disrupted, measured across 6 Julys in the archive. February has been the calmest, at 18.8% across 7 Februarys.
Even July has ranged from 40.5% to 58.0% in different years, so this is a record of what happened, not a forecast of what will. Lower is better throughout.
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.

The matrix shows the last eight calendar years, including an incomplete final year; the start of the archive is kept in the history above. Seasonal summaries use the whole available archive, excluding the pandemic regime 2020–2021; this is an observed range, not a forecast. Zero events, missing data and suppressed cells are marked separately. † marks a small sample, described but not ranked. For ranges the colour follows the upper bound.
Which airline has the better record here?
On the published record there is no clear winner: Ryanair 33.7% of 1,371 movements, Ryanair Uk 35.7% of 28 movements — small sample, not ranked. Not enough comparable carriers.
Figures cover arrivals, July 2025 to June 2026; lower is better in every column. Carriers with fewer than twenty published flights are suppressed rather than shown as zero. The page makes no ranking: the operations behind these shares are not matched for aircraft, time of day or season.

Would another UK airport have been better?
Among UK airports flying to this city with enough flights to publish, LGW had the lowest disruption share at 15.3% of 1,953 movements and LTN the highest at 41.8% of 294 movements. This route sits at 33.7% of 1,400 movements.
Each figure is arrivals into that UK airport, all carriers combined, over the same twelve months. It is a historical record, not a recommendation about where to fly from, and it says nothing about getting to or from each airport on the ground.

Does the direction you are flying change anything?
Yes: arrivals into STN ran 33.7% of 1,400 movements disrupted, departures 42.8% of 1,398 movements.
It matters legally as well as practically: a departure from the UK and an arrival into the UK on a UK or EU carrier fall under different conditions, and a departure delay does not establish a late arrival at your final destination.

How many flights here crossed the three-hour mark?
The table below counts arrivals and departures that ran more than three hours late — the threshold that is one of the conditions for compensation — across the whole archive and within the last six years.
The pound figure beside each count is arithmetic, not money anyone received: it is the count multiplied by the maximum statutory amount for this distance band. Whether any of those flights actually qualified is not knowable from this data.
| Direction | Window | Flights over three hours | Arithmetic statutory ceiling |
|---|---|---|---|
| Arrivals | Whole archive · Jan 2018–Jun 2026 | 65 flights out of 9,622 | 65 × £220 = £14,300 |
| Arrivals | Last 72 months · Jul 2020–Jun 2026 | 37 flights out of 6,452 | 37 × £220 = £8,140 |
| Departures | Whole archive · Jan 2018–Jun 2026 | 37 flights out of 9,627 | 37 × £220 = £8,140 |
| Departures | Last 72 months · Jul 2020–Jun 2026 | 25 flights out of 6,454 | 25 × £220 = £5,500 |
Definitions, denominators and limits
Full formula: the count is the sum of the two tail buckets across months, carriers and service types in one direction; the ceiling is that count multiplied by the maximum statutory amount for the distance band. The condition is: if every such delay had been the carrier's fault and a claim had been filed on every one of them.
This is conditional arithmetic over operations: passenger numbers, legal applicability and the number of claims are all unknown. For departures it is an arithmetic scenario only, because arrival at the final point is not observed. For long routes the maximum ceiling is used; any reduction in the payable amount is not calculated.
The archive window is counted from the last month of data, not from today: this is not a limitation check for an individual case. The CAA states six years for England and Wales and five for Scotland. CAA: time limits and how to complain. Information, not a legal service.

What this data cannot tell you
Delay cause is not published in the regulator's open data. Monthly aggregates describe a population, not a specific flight. Cells below twenty operations are suppressed; twenty to forty-nine are descriptive only and not ranked. Arrivals and departures do not add up. Cancellations are short-notice only, by the CAA definition. A movement is not the same as a scheduled flight.
0 operations (0.00%) excluded because their published percentages could not be reconciled to whole numbers. Excluded operations enter neither the numerator nor the denominator. Outcome figures and comparisons are unavailable when the excluded share exceeds fifteen percent.
Data-quality counters for this route
Zero observed events does not mean zero risk. Operator coverage against the Summary file is not established in this record; comparisons are limited to the published population.
Unmatched records: 1; all recorded operations: 1,401; excluded by quarantine: 0.
Quick answers
How often is this route disrupted?
33.7% of 1,400 movements over July 2025 to June 2026. Arrivals into the UK airport; all published carriers.
How many flights are cancelled at short notice?
no events in 1,400 movements in the same window.
How many delays crossed three hours?
0.5% of 1,400 movements in the same window; these are observed movements, not a count of claims.
What does the delay distribution look like?
chronically slightly late. The class compares the tail with short delays across routes in the corpus.
What distance is used?
1,300 km, great-circle.
Can compensation entitlement be established here?
No. The cause and the circumstances of an individual flight are unknown. Official CAA conditions.
Why do some cells say "no data"?

How this was calculated
Dataset version, input hashes and reconstruction rules
Dataset version: 396da8dde2874f14; method route-record-v2.1.
Versioned register of every number and the entity map · Input hashes · Correction log · Reconstruction and formulas.
Reconstruction: integer counts inside the rounding bounds of shares of D, summing to M. Ambiguity is preserved as a range of feasible counts; non-convergence stays in quarantine. The map of codes and coordinates is pinned by hash alongside the data. Raw CSV files are not included in the published output.
