Dear Nancy,
As you may know, there's been a vulcano eruption in Iceland. The winds are blowing the vulcanic ash over western and northern Europe (including the UK). Therefor the airspace above the UK and the Netherlands in your husbands case, are closed untill further notice. Flights heading south from Amsterdam are delayed heavily. London Heathrow cancelled all flights.
The vulcanic ash can jam the jet engines, causing them to fail. This risk is obviously too big to keep flying.
But, some flights are being rerouted as we speak, since it is possible to fly south and cross the atlantic ocean near Portugal and Spain.
It is unclear at this point when the eruptions will end, and when the airspace is save again.
With kind regards,
AMS int.
