United Continental expects to cut some management employees as a part of its larger restructuring program.
"While we don't have an exact figure now, a small number of our management team will be affected by reductions," said spokeswoman Megan McCarthy in a statement.
However, frontline employees, which include pilots, flight attendants, customer-service and gate agents, would not be affected by the impending changes, she said.
The No.3 U.S. airline by passenger traffic is increasing efforts to match margins of No.2 Delta Air Lines.
United said in October cheap airfares and higher wages from new contracts would squeeze its results in the fall, making it difficult to be as profitable as competitors.
Bloomberg earlier reported the staffing cuts.
