The company's fourth quarter revenues grew 10.7% to $2.9 billion as operating income jumped from $14 million to $105 million.
Fourth quarter expenses at US Airways grew 7.3% to $2.8 billion, driven largely by a 22.4% in fuel expense to $628 million.
Unlike most US carriers, US Airways has opted not to participate in a fuel hedging programme, reasoning that overall the schemes are expensive.
