I have personally heard of many people who have cancelled travel plans. Some were only planning to travel domestically. A lot of people don't want to go anywhere near the airport. It may seem silly to us as crew/airport employees that people are behaving this way, however this is how the general public are perceiving the situation. I think all flights will be affected, not only flights to the US or Japan etc. I think this swine flu pandemic will have a big impact on domestic travel too.
