JAL faced massive debts when it collapsed in January
Japan Airlines (JAL), which entered bankruptcy protection last month, has announced a massive increase in loses.
The airline said it lost 177.9bn yen ($1.99bn, £1.3bn) in the last nine months of 2009 - up from a loss of 1.9bn yen a year earlier.
JAL is continuing to operate flights while it undergoes major restructuring under court supervision.
The company is expected to cut staff, routes and aircraft numbers in an attempt to return to profitability.
Reflecting on the company's failure, JAL said it was "deeply apologetic" for the situation that shareholders, creditors and customers now found themselves in.
"[We are] working fervently... to draw up an effective corporate revitalisation plan to rebuild the airline, while continuing to provide safe and stable flight operations and services to customers," the airline said in a statement.
JAL collapsed earlier this year after racking up $16.5bn in debts.
It is one of the most high-profile airlines to fall victim to the global recession, which caused a collapse in passenger numbers and left many airlines facing big losses.
