My girlfriend is headed SFO-BOS on ATA this Friday. They just called to tell her that there has been a schedule change on ATA and will cause her to have about a eight hour layover at MDW. ATA is telling her that there is no way they can get her on another flight. Can anyone point me to the DOT rules on flights changing from the airline as opposed to an "act of god." I know that they will change their tune as soon as I can bring up the government rules on the issue. Thanks in advance, tyler
