It's an appalling situation, with hundreds of thousands of people stranded at airports throughout the world, not knowing when they'll be able to travel or return to their home countries. Many of these can't afford additional hotel costs, and are just stuck at the airport.
There's a lot of uncertainty about whether or not travel insurance companies will cover alternative travel costs, or additional accommodation costs, apparently claiming this is all an uninsured 'Act of God'!
My wife and I are due to fly from London to Turkey in three weeks time, but if this situation goes on, we'll have to cancel the trip - and no doubt lose the money we've paid. That is unless the tour company or the airline don't cancel it first.
Another important aspect, which I've not seen reported anywhere, is deciding whether or not to travel, even if flights resume. There may be a temporary windshift, which takes the volcanic dust cloud towards the north, and away from continental Europe, thus allowing planes to take off. What happens though, if the eruption continues and the wind shifts back again - you're stuck, so maybe best to not fly out at all, unless you're returning home. All very difficult
