As most of you probably have already heard, a volcano under the Eyjafjallajokull glacier in Iceland erupted on Wednesday, sending smoke, steam and volcanic ash into the air and causing flight disruptions across the UK and Europe.
Originally, no flights are allowed to fly in and out of British airspace until at least 7AM on Friday, 16 April. However, the BBC just reported that the International Civil Aviation Organisation could potentially ground flights for another 48 hours, depending on where the ash goes (http://news.bbc.co.uk/2/hi/europe/8623534.stm).
If your flight is cancelled due to this event, you should be offered either a refund or the option of rebooking on a new flight with your airline.
If you have a flight scheduled for the next few days, be sure to check with either your airline or airport’s Web site on whether travel has resumed. Additionally, be prepared to encounter potential delays even if flights resume the day of your flight, as the airlines would be scrambling to accommodate passengers whose flights were cancelled.
