A formal Department of Transportation complaint has been filed (.pdf) against American Airlines over the removal of their general tariff from their website in June.
American used to have its full ‘terms and conditions’ available online. They’ve removed the legalese entirely from their website and now offer a plain language FAQ-style conditions of carriage page. However there’s still a general tariff, and customers effectively agree to it when they buy a ticket. They just can’t see it or read it.
