Increasing numbers of passengers travelled on flights from UK and European airports between January and March compared to the same period last year.
This is according to findings from Airports Council International (ACI) Europe, which reported a 5.2 percent increase during the first quarter of 2010.
Olivier Jankovec, ACI Europe’s director general, said it is "encouraging" that more than 80 percent of Europe’s airports have reported a growth in passenger numbers over the three month period.
"However, the paralysis caused by the massive closure of airspace in response to volcanic ash dispersion has seen Europe’s airports losing up to 25 percent of their traffic in April," he explained.
"This is an extremely severe shock to our recovery, which is still evolving."
March was a particularly positive month for passenger growth, when a 6.9 percent rise was recorded compared to the same month in 2009.
Separate ACI figures recently revealed a 5.9 percent decline in the number of passengers using North American airports in 2009 compared to 2008.
