As airline losses from the volcanic ash cloud spiraled over $1 billion on Monday, the industry demanded EU compensation and criticized European governments for not using scientific measures to evaluate the ash and open up their airspace.

Shares of some European airlines fell as flight disruptions from the volcanic cloud moved into a fifth day, and the International Air Transport Association complained of "no leadership" from government leaders — one of whom admitted to EU dissension about how to respond.

"It's embarrassing, and a European mess," IATA CEO Giovanni Bisignani told The Associated Press. "It took five days to organize a conference call with the ministers of transport and we are losing $200 million per day (and) 750,000 passengers are stranded all over. Does it make sense?"

European civil aviation authorities held a conference call Monday about what steps could be taken toward opening airspace, and transport ministers from all 27 EU member states were to hold another later in the day.

Dominique Bussereau, France's transport minister, told reporters Monday that he had urged EU president Spain ever since Saturday to call the ministerial meeting immediately — but Madrid declined.
