I hate to break it to the bankruptcy conspiracy theorists, but the bankruptcy laws have been changed drastically in recent years. Thanks to the outright abuse of the system by the likes of UAL, NWA, DAL and others, it now takes a much higher standard for a corporation to declare bankruptcy. The aforementioned airlines used the bankruptcy laws and courts as a tool to gut contracts (including union contracts), but the new laws are designed to prevent that from happening again. Besides, it will be very tough for AMR to approach the bankruptcy threashold given solid profits and a great deal of assets.
