London City is the UK’s most punctual airport while Heathrow is the place where flights are most likely to be delayed, according to latest figures from the Civil Aviation Authority.
Across all 10 airports monitored last year, 80% of flights were on time, but at London City 89% were on time and at Heathrow 24% were delayed.
The average delay across all scheduled flights monitored in the last quarter was 12 minutes, which was the same as in the previous year.
However, the on-time performance of charter flights improved by three percentage points and the average delay fell by four minutes.
In the fourth quarter of 2013, there were 324,000 scheduled and 13,000 charter passenger flights at the 10 airports, a 2.7% increase in the number of scheduled flights and a 0.7% fall in the number of charters compared with the same period of the 2012.
Iain Osborne, group director for regulatory policy at the CAA, said: "Whilst it is pleasing to see the majority of passengers arrived at their destination in good time at the end of last year, our figures show that too many people still had their flights disrupted by delays.
"We also know there were a number of cancellations during December that will have disrupted other passengers.
"Some severe weather clearly played a part in this, but there is still room for improvement. Airports, airlines and air traffic control service providers all have a role to play in delivering that improvement and it is vital they work together to make sure fewer passengers have their journeys disrupted by delays and cancellations
