Transatlantic flights are still operating with delays due to the ash plume from the Eyjafjollajokull volcano in Iceland, air traffic control authorities said May 10.

The huge body of ash hanging over the Atlantic means that while most flights are operating, many are having to make significant reroutings to avoid the area of ash cloud coverage, resulting in delays.

Around 1,500 flights were cancelled in Europe on Sunday, May 9 due to the ash, which moved across the Iberian peninsula and the south of France, said Eurocontrol.

Current forecasts show that the ash could move in a northeasterly direction across the Iberian Peninsula again this afternoon, potentially closing airports that reopened this morning.

Data from Iceland's meteorological office suggests that the volcano is still erupting.
