United Airlines (UAL) has posted positive full-year results, after a strong December, with a net income of $1.084 billion, rising 84% from 2012.
Including special charges, the overall profit for the year was $571 million.
Total revenue in 2013 also rose 3% to $38.3 billion due to a rise in fares and ancillary fees.
Fuel costs also fell during the last quarter by 4%.
United also said its employee profit-share scheme had amassed $190 million and will be paid out on February 14.
This is in addition to a cash incentive scheme of up to $100 a month which is awarded when the carrier meets on-time performance targets during the year.
During 2013 this amounted to $54 million, the company said.
Last year the airline announced measures to cut costs by up to $2 billion as it continues to streamline operations after the 2010 merger with Continental.
Part of these cost-cutting measures include furloughing up to 700 flight attendants, which the company announced last week.
The carrier said operating costs in the fourth quarter fell by $73 million.
