Eruption safety.
I should say, definitely not.
The essential thing about an eruption is that it is UNPEDICTABLE.
The amount of gunk it is spewing out at this moment may indeed be minor, (although I don't think I should like this stuff flowing through MY engines and sand-blasting their insides,) however at a moment's notice it could decide to erupt big-time again, when aircraft are actually in the air not too far away.
I suppose they could reduce the size of the no-fly zone to some extent. But I feel it is safest to let it die down completely, because only then will we have any reasonable certainty that it will remain safe.
