“We thank our team for taking care of our customers during the busy holiday travel period.
“Their efforts led to significant improvements in key operational metrics and great customer service.
“We also completed a number of important merger integration projects that will serve us well in the future,” American Airlines chairman Doug Parker said.
He added: “We enter 2019 with great momentum.
“We are intent upon running the most reliable operation in our post-merger history, pursuing high margin growth opportunities at our most profitable hubs, and executing on a number of valuable revenue and cost saving initiatives.
“We expect our total revenue per available seat mile to grow faster than our network competitors, and to deliver strong pre-tax earnings growth in 2019.
“At the midpoint of our guidance, 2019 diluted earnings per share excluding special items would increase approximately 40 percent versus 2018.”
