Most European airports reopen, some see ash delays

Aviation authorities introduced relaxed flight safety rules Monday to minimize more disruptions caused by a volcano eruption in Iceland, as three of Europe's busiest airports reopened after a dense volcanic ash cloud dissipated.

Britain's Civil Aviation Authority said it agreed with airlines, regulators and engine manufacturers on new rules that would let planes fly for a limited time at higher ash densities than currently allowed. The rules - which go into effect Tuesday -_ are subject to airlines getting a guarantee from their engine makers that their aircraft can safely tolerate the ash. (AP)
