Last point first: they may be losing millions a day. But they are earning those same millions a day for 365 days per year.
It's no worse for airlines and airports to 'have a few days off' than for anyone else. So absolutely nothing to worry about there.
Like you, i'm in one of those countries the ash is supposed to be over. Besides airports being closed, air traffic halted, we haven't noticed anything of it yet. Not the promised extra colourful sunrises and sunsets. No haze to spoil the blue skies we have been enjoying this week.
That's not implying that there is no ash drifting somewhere. But the reports are grossely exagerated. Why, even gliders are grounded! (And you know how high they go, and how many engines they have that could fail.)
There's a habit of blowing everything that could be bad up out of every proportion lately (Remember the swine flu anyone?). This is one of those thingies.
It will not take long for this madness to blow over (pun intended) and for air traffic to start up again.
And we will still be wanting our money back from Iceland.
