Passengers may be refused compensation if their flight is cancelled because of a volcanic eruption.
Yesterday Europe's most active volcano, Mount Etna, spewed a huge dark cloud into the sky, raining ash down on Catania, eastern Sicily's largest city, and forcing a suspension of flights at the city's airport.
No injuries have been reported following the blast, which caused a great plume of molten liquid to fire out of the mountain. Ash was seen raining down and covering cars near the volcano.
