text:  Some of the biggest US airlines have grounded their planes. And in Europe, several airports, including Amsterdam, Berlin and Zurich, cancelled early morning flights. Dean Seddon was supposed to be flying to Miami this morning from London's Gatwick Airport. When we arrived, there was nobody in our queue. Now, you can't even walk to the back of the check-in desk because it's just full of people. There's people sat in suitcases in the kind of queue barriers.
