Now we get a discussion of how close to reality the computer model is for this event!

From a comment we have the BBC:

EU moves to ease Europe flight curbs

And:

***********************EXCERPT*************************************

According to current European regulations, no matter how low the concentration of ash, no commercial aircraft should fly as long as it is in their path.

A spokesperson from from Nats told BBC News that there was "no threshold" for concentrations at which volcanic ash was acceptable.

The dust is simply too dangerous for jet engines to risk commercial flights encountering it, said Nats. If volcanic ash particles are ingested into a jet engine, they accumulate and clog it with molten glass, which can cause the engine to shut down.

This is a mixed bag. If planes where to experience in-flight engine failures, other related incidents, e.g. frosted cockpits etc., then someones head would roll. I can see their collective initial concerns. It was not unreasonable.
Perhaps this time around I'll stay neutral on the issue. Even though I read parts of WUWT site... "MET office, computer models".
