European flights are operating as normal after volcanic ash from an Icelandic volcano, which had threatened to cause widespread cancellations, dispersed.
According to Eurocontrol, no significant disruptions of air traffic are expected in Europe in over the next few days as a result of volcanic activity.
The air traffic agency said activity from Iceland's Grimsvotn volcano has declined sharply.
According to the Volcanic Ash Advisory Centre (VAAC) in London, no airspace is closed due to volcanic ash and flights throughout Europe are operating as normal.
The Irish Aviation Authority says all airports in Ireland and Northern Ireland are operating as normal and there will be no impact on Irish airspace for at least the next 48 hours.
In total, around 900 flights were cancelled in Europe between Monday and Wednesday.
Some ash concentrations continued over small parts of northern Scandinavia and northern Russia early on Thursday.
Geophysicists say Iceland's volcano is still active, but producing mostly steam rather than ash.
