American Airlines saw net profits climb for 2013 on the back of its merger with US Airways.
The American Airlines Group combined net profit was $1.9 billion, up from $407 million in 2012, excluding special charges.
Profit for the fourth quarter of last year came in at $436 million against a loss of $42 million in the same final three months of 2012
American Airlines Group was born last month after American Airlines exited bankruptcy and merged with US Airways.
Group chief executive Doug Parker said: “The early returns on our merger are very positive.
“Our teams are working well together and our customers are already beginning to see the benefits of our combined network.
“We have much work ahead, but believe we are on our way to restoring American as the greatest airline in the world.”
He added: “These financial results are evidence of the strong foundation we have in place and we anticipate improving upon these results as we further integrate our operations in 2014.”
