Punctuality statistics 2017

Punctuality statistics are calculated for 25 UK Airports. The planned time of operation is obtained from the airport scheduling committees and merged in with the actual time of operation on the air transport movement records collected in UK Airport Statistics. Information is published each month which shows the average delays on scheduled and charter services at each of the airports both in total and at an individual route/airline level.

Southend is being included for the first time from April 2016.

It should be noted that the statistics in this notice cover only those flights which were operated; they do not cover those flights which were cancelled. Some airport or airline business models prioritise delaying flights rather than cancelling them outright.

The information contained in these reports have been compiled from various sources of data. CAA validates this data, however, no warranty is given as to its accuracy, integrity or reliability. CAA cannot accept liability for any financial loss caused by a person’s reliance on any of these statistics. No statistical data provided by CAA may be sold on to a third party. CAA insists that they are referenced in any publication that makes reference to CAA Statistics.

Note the following:

• With effect from April 2016, Birmingham and Belfast International Airports actual time of operation has changed from the arrival/departure at the stand to the wheels on/off the runway. As the planned time of operation relates to the arrival/departure at the stand, estimate Taxi Times have been built in Birmingham, 10 minutes (arrivals and departures), Belfast International, 5 minutes (arrivals and departures), which have been provided by the airports. We will continue to analyse the results and reserve the right to adjust the reports accordingly. When evaluating year on year comparisons use figures from the previous year file, as results recorded for previous year in the latest file will not provide an accurate comparison.
• April and May reports have been updated.

How to contact us

If you have feedback on our published reports contact Aviation.Intelligence@caa.co.uk. You will receive an automated reply confirming that we have received your comments.

We review every comment that we receive and, if significant issues are found with our published reporting, reports will be amended and re-published. Unfortunately, we are unable to respond to individual queries.

With effect from April 2016 data, 'planned data' allocated by Airport Coordination Limited can be provided by the airports themselves. As the planned data is also provided directly from Airport Coordination Limited this data appears in reports as unmatched. We are therefore no longer monitoring the 'number of unmatched planned' records. We would advise that this information is used with care. If there are further queries concerning any particular airport please contact us at aviation.intelligence@caa.co.uk.

We have identified an issue with the PDF version of the Punctuality Analysis. We are investigating and will resume publishing of this format as soon as the issue has been resolved.

As at 29 May 2018, November, December and the Annual tables have been updated and now include data for Southend airport.
