Yes, but ATA hasn't exactly put -anything- on their website, either, in terms of their financial woes.
While financial pressures are seldom addressed on public company websites, an actual BK filing would be part of their press releases.
Also, as others have mentioned, carriers who file for bankruptcy typically use their websites to convey a message of, "this is just a formality - it's business as usual here at XYZ Air Lines," to reassure the traveling public that it's still safe to book them.
