Losses at US Airways have proved smaller than feared in its first quarterly report since merging with America West in September 2005.
The two airlines joined last September
For the three months to 31 December, the combined group made a loss excluding one-off costs of $138m (£79m), or $1.72 per share.
Analysts' expectations for the loss had averaged $1.89 per share.
Although the firm is still called US Airways, it is dominated by ex-America West executives.
"Looking forward, we continue to believe that excluding one-timer merger-related transaction costs, the new US Airways will be profitable in 2006 - even at today's projected fuel prices," said chief executive Doug Parker.
Quarterly revenues at the group, the sixth largest airline in the US, totalled $2.6bn.
The old US Airways had to seek bankruptcy protection twice in two years prior to the merger.
