followed as runner-up for the season, with a 50% reduction in average delay from 40 minutes in summer 2008 to 20 minutes in summer 2009, and close to 20 percentage points improvement in on-time performance from 54% to 73%. The airline slashed the proportion of flights operating over an hour late from over 16% in summer 2008 to less than 8% in summer 2009, and the proportion of flights suffering extensive delays also fell sharply from over 5% in 2008 to less than 2% in 2009.
At Birmingham, where Monarch was the most punctual charter airline during summer 2009, an average delay of just over 5 minutes and nearly 91% on-time performance was recorded, the best performance seen for any charter airline at an individual airport during the season.
Despite having the second highest on-time performance at 76%, Thomas Cook Airlines
finished the season in third position with a close to 40% reduction in average delay from 35 minutes in summer 2008 to 21 minutes in summer 2009. A much higher proportion of delays in excess of 1 hour compared with the average for all charter flights during the season, at 1 in 10 flights, adversely affected the average delay for Thomas Cook charter flights.
, a relative newcomer to the UK charter market in summer 2009, demonstrated the poorest punctuality during the summer 2009 season, with their average charter flight delayed by nearly 40 minutes, around double the average for all charter flights during the period. Less than half of all Viking flights operated on time and a high proportion, 1 in 6 flights, was delayed by over an hour - twice as many as the UK charter average.
