April 2011 traffic figures show 25.6% jump on previous year due to ash cloud effect

17 May 2011

The number of UK flights increased by 25.6% in April 2011, in comparison to the same month the previous year when traffic was severely affected by volcanic ash. However, the estimated underlying change for the month, ignoring the impact of the volcano, was a decrease of 0.4%.

Figures were also affected by the additional Bank Holiday and the fact that there were two fewer working days in April 2011 than April 2010. Both factors would tend to reduce traffic volume.

All centres and markets show similarly large growth rates due to comparison against last year’s very low numbers.
