SriLankan Airlines announced that all its flights to Europe will depart as scheduled with a contingency plan to fly to alternate airports in case Iceland’s volcanic ash clouds spread further into Europe.

Passengers bound for London, Frankfurt, Paris, Rome and Milan are advised to call the SriLankan Airlines contact centre on 1979 for information about their flights six hours before departure.

The airline is closely monitoring the developments of Iceland’s volcanic eruption and its ash clouds which may spread further in Europe. Passengers can call SriLankan Airlines contact centre on 1979 from any telephone or mobile network and be kept informed of any changes in their flight schedules during this period.

The ash from the Grimsvotn volcano in Iceland that began erupting on Saturday has forced the aviation authorities to cancel flights across northern Europe.

According to an Associated Press report between 200 and 250 flights had already been canceled, and authorities have warned that up to 500 flights could be affected.
