About 500 flights were cancelled as an ash cloud from an Icelandic volcano closed parts of the airspace above the UK, European air traffic controller Eurocontrol said on Tuesday.
Eurocontrol said there was a strong possibility the cloud would move to parts of Denmark, Norway and Sweden, but impact on flights would be limited.
In some good news, experts said the air industry need not worry about a repeat of the 2010 volcanic eruption that grounded tens of thousands of flights. Iceland’s Met office, too, said the eruption at the Grimsvotn volcano looked like it was running out of steam.
However, experts warned airlines against “experimenting” by flying planes through skies filled with ash. The warning came after budget carrier Ryanair flew into an ash zone to show it was safe to do so.
