I recall reading in a U.S. newspaper about a year ago that U.S. airlines can record employee's good or bad comments about passengers in their information systems. When a customer service rep pulls up your information at the gate terminal, they know if you've been bad or good, and can discipline or reward you. I regret I don't have a citation for the article. U.S. privacy rules are less protective of individuals than similar rules in Europe, the UK, and Scandanavia. I agree that unruly travelers should have their air travel rights banned or suspended.
