"A report on UK Channel 4 news http://www.channel4.com/news/articles/uk/ash+flight+ban+to+remain+over+most+of+uk/3620597 states that 26 British Airways 747's have taken off from around the world and are heading for the UK, despite being told it is still closed. This is apparently part of an 'aggressive strategy' to remove the ban and get 'planes flying again on the part of the airlines."

This is a cool vid... http://http.ruv.straumar.is/static.ruv.is/vefur/20042010_myndir_omar.wmv See the ripples in the ash clouds - they are shock waves.
I've heard one plane come in to Aberdeen airport and that was around 8:30-9am I think. Been quiet since apart from a howling gale & rain/sleet/hail. D'oh, as I write that I hear another coming over - just a small plane though, not a jet.
If they do I think it may be at 'low enough concentrations' that they feel money loss outweights safety. Some places are clear, I think - take a look at the meto predictions charts and see.
As was mentioned earlier I think, flying above a certain height is ok (above the ash) but take off & landing (i.e. going through the ash) is not ok. So planes can go over us but not down or up from the ground.
Watching from your own home isn't the same tho'... no weird smell for a start. Well, not from a volcano anyway.
It's hard not to be interested in this stuff in my case - studied Geology at Uni.
Keep an eye on the Vodapnone images on the Google/Picasa site images - now it is dark you can see (on the right hand image) a red glow at the base of the plume - lava or fire of some sort.

Something I've noticed the last few nights is that Venus is twinkling (not something planets usually do, only stars). Dust in the atmosphere do you think?
http://www.jonfr.com/ He's had a look and says Hekla is sleeping like a babe at the moment. Earthquake swarms are a sign of trouble for this one. Good blog - he's one of the regular contributors to the Eruptions site and has his own seismometers: http://www.simnet.is/jonfr500/earthquake/tremoren.htm
As I suspected, apparently the Hekla cam was repositioned a day or so ago to watch Eyja. THIS is Hekla: http://www.webcamsmania.com/webcam/heklavolcano
Those worrying about getting flights out of the country might also do well to think about how they'd get home should this recur and maybe do some research so they have contingency plans should they be required.

Apologies, didn't see it - digging in garden now the snow has stopped falling here, and coming in every so often to check out what's going on. Not had chance to look at everything but posting stuff I come across thast might be interesting.
Enjoy:
Ignore the ad at the start and watch for the volcanic bombs flying out.
