Credit crunch and empty airport terminals

I had a share of extensive travel during September and October earlier this year. It was interesting to see empty airport terminals during some of these travels. A claim could be that the credit crunch has had a decisive affect on the decrease on number of travellers. It could also be the case that these terminals were not serving full capacity on the bizarre days and times I used them, or that the people have become more environmentally conscious, but I think the reasoning behind credit crunch is somewhat realistic and even so more dramatic when one is exposed to such sights as the following:
