The reality is that if you haven't lost your job, then whilst you may have taken a direct or indirect paycut(ie wages cut and the levys), then that is partially offset by the decline in prices in the country. Hence, for many people, the recession has not had a major day to day impact on their cashflow. People may be more cautious and looking for a bargain, but it doesn't mean to say that a lot of people don't have the money to travel.
If the volcano had erupted 4 years ago though, you would have had more people stranded in more exotic locations then now
