Some 17,000 flights in European airspace are likely to be cancelled Friday due to the dangers posed by a volcanic ash cloud spreading from Iceland, with experts warning that the disruption could continue into the weekend.
Although some Scottish and Scandinavian airports are likely to resume limited flights Friday, a ban on flights still covers most UK airspace and much of Northern Europe.
Eurostar has also confirmed that it has no availability for trains on Friday, April 16.
