Profits after taxation rocketed 48.7 percent to 139.3 million euros ($199.7 million) in the three months to June, compared with 93.7 million euros in the same part of 2010, Ryanair said in a results statement.

However, last year's first-quarter profit was hit by a 44.8-million-euro charge relating to the closure of European airspace. Stripping this out, net profit this year rose by just one percent.

Ryanair added on Monday that passenger numbers rallied 18 percent to 21.3 million people over the reporting period, helping push group revenues up 29 percent to 1.15 billion euros.

At the same time, fuel costs jumped by 49 percent to 427 million euros amid stubbornly high oil prices. Jet fuel or kerosene is derived from crude oil.

Ryanair Chief Executive Michael O'Leary said traffic volumes were skewed by the impact of the Icelandic volcanic ash cloud which had sparked massive disruption to European air travel last year.
