US Airways is trying to stay afloat through cuts in labor costs, cooperative creditors and vendors, and access to about $700 million worth of federally guaranteed loans backed by the Air Transportation Stabilization Board. Most of its assets are pledged as loan collateral.
The ATSB agreement expires Jan. 15. If the ATSB refuses to grant an extension, US Airways will be forced to shut down immediately.
