Updated list of airport closures at http://www.nytimes.com/interactive/2...s-graphic.html .

Interesting to see that ash cloud covers seems to be similar in Moscow and St Pete as in some other parts of Europe, but these airports are still powering through (as as discussed earlier, with airlines that use Western aircraft in many cases) with no adverse reports or findings yet.

It is quite clear that the cloud is not stopping at the Russian border!
