A consumer advocate is suing Delta Air Lines for allegedly hacking computer information she was compiling to win passage of an Airline Passenger Bill of Rights in Congress. Kathleen Hanni, founder of Flyersrights.org, says the computer infiltration occurred after she had gathered data on Delta flight delays from Frederick Foreman, an employee of Metron Aviation. She determined Delta was behind the hacking because Metron confronted Foreman with copies of the files lifted from Hanni’s AOL email account. Foreman was then fired by his employer, which also is being sued by Hanni, who is seeking $10 million in damages.
