RE: How to score cheap business and even first-class flights

Never thought of using this method but then you have to be very flexible and that does not really work when you are planning ahead. I have been accumulating points to the extent I have enough to upgrade or even get free tickets for international flights so I am looking forward to when that happens next flight. The walking around late at night when everyone has gone to bed also works as long as there is empty seats in business class.
