The disruption has affected hundreds of thousands of travellers since Wednesday when the Eyjafjallajokull volcano began erupting for the second time in a month, hurling a plume of ash 11km (seven miles) into the atmosphere.
Even scarier, a New York Times article reports that in a similar event in Iceland almost 200 years ago, the volcano continued erupting for almost two years.
It was unclear when the situation would end, because the volcano was still erupting and spewing ash Saturday, said Agust Gunnar Gylfason, a project manager at Iceland's Department of Civil Protection and Emergency Management.
