Multiple outlets report that the UK’s worst-performing airports for flight delays have been identified through analysis of Civil Aviation Authority (CAA) data compiled by the Press Association. The coverage is based on 2025 performance, using average departure delay against scheduled times. One report highlights that departures from a major UK airport are, on average, about 19.5 minutes behind schedule in 2025, citing the CAA-based analysis. Other outlets describe the exercise as a ranking of airports by delay performance, focusing on which airports experience the greatest average delays for departures. While the articles agree on the overall finding—that airports can be ranked by flight-delay performance and that at least one airport shows an average delay of roughly 19.5 minutes—details such as the full list order and which specific airport is worst are not fully reproduced in the provided excerpts. Overall, the reporting frames the results as a data-driven comparison of airport punctuality, drawing exclusively on CAA records and presenting the outcome as a “worst airports” ranking.
