The CAA says the Midlands airport recorded the best overall flight punctuality of any operating both scheduled and full service charter flights.
During the busiest period of the year from July to September, 88% of scheduled flights and 90% of charter services operated on-time at Birmingham.
London Gatwick recorded 75% on scheduled flights and 74% on charter flights, while London Stansted achieved 85% on scheduled and 85% on charter and London Luton 83% on scheduled and 87% on charter.
The CAA also says Birmingham had the biggest increase in flight on-time performance out of any UK airport – 6% points on scheduled services and 5% points on charter flights - compared to the same quarter of 2012.
Birmingham Airport also reduced the length of delays from 11 minutes to eight on scheduled services and from nine minutes to eight on charter flights, compared to Q3 2012 - the shortest delays of any UK airport outside of London.
Paul Kehoe, Birmingham Airport’s CEO, says: “These results are testament to the team effort at Birmingham and the hard work that’s been put in over the last few years to deliver a world class airport.
“We’re therefore really proud to have come top of the punctuality charts for Q3 2013 and hope that this demonstrates, to those who have not yet experienced what Birmingham has to offer, the benefit of travelling through an efficient and convenient airport.”
