European airlines test skies, press to end ban

AMSTERDAM – Major airlines that sent test flights into European air space found no damage Sunday from the volcanic ash that has paralyzed aviation over the continent, raising pressure on governments to ease restrictions that have thrown global travel and commerce into chaos.
Is it safe to fly yet? Airline officials and some pilots say the passengerless test flights show that it is. Meteorologists warn that the skies over Europe remain unstable from an Icelandic volcano that continues to spew ash capable of knocking out jet engines.
European Union officials said air traffic could return to half its normal level on Monday if the dense cloud begins to dissipate. Germany allowed some flights to resume.
