A three million euro fine has been slapped on the low-budget Irish airline Ryanair by Italian authorities.
The Italian Civil Aviation Authority claims the company did not meet its legal obligations to passengers in 178 cases during the chaos caused by the volcanic ash cloud.
The agency has ruled that Ryanair did not provide drinks, food and hotel accommodation, as required by law when flights are cancelled.
The complaints relate to flights operating out of Italian airports between April 17 and 22.
The news comes as Europe has been facing more disruption from the ash cloud coming from the Iceland volcano.
There is a warning today that parts of British airspace may have to close from Sunday until Tuesday.
