The UK Civil Aviation Authority has expanded its airport punctuality monitoring to now track 24 high-traffic airports across the country, more than doubling the number of airports monitored. The regulatory body will monitor average delays and on-time performance for both larger airports like Heathrow as well as smaller regional airports. This update will allow passengers to compare punctuality for 90% of all flights, up from 73% previously, and monitor 97% of all passenger journeys. The CAA began collecting data from the new airports in October 2014 to provide a comprehensive fourth quarter report and year-on-year comparisons.
