Spanish tourism lost 252 million euros ($339 million) over six days because of travel restrictions caused by the volcanic ash cloud which grounded air traffic in Europe, industry body Exceltur said on Wednesday.
Tourism accounts for around 11 percent of Spain’s gross domestic product.
Airline losses are not included in the overall figure but it was not clear whether this figure took account of gains from hosting tourists forced to stay in Spain after their flights home were cancelled.
No one at the institute was immediately available to comment.
The Icelandic volcano is still erupting but is spewing less ash, experts said on Wednesday. The cloud of ash has not reached Madrid and the airport has remained open.
The British Embassy was operating a stand at Madrid’s Barajas airport to take passengers, who had flown into Madrid, up to northern France by bus to catch a ferry back to Britain.
There are no economy-class flights available from Madrid to London until May, the website of airline Iberia showed.
