American Airlines (AA, Dallas/Fort Worth) has announced it will eliminate an undisclosed number of managerial posts as it nears the completion of the merger with US Airways (Phoenix Sky Harbor), Bloomberg has reported.

"While not all integration work is complete, much of it is and as a result, now is the right time to look at the organizational structure we need for the future," Chief Executive Officer Doug Parker and President Robert Isom have written in an internal memo.

Out of American's 128,000 staff, some 12,000 are involved in the management. The cuts will not affect any employees who directly interact with passengers. Most of the layoffs are expected to happen through attrition or by leaving currently open positions unfilled.

The carrier plans to integrate the two crew planning systems on October 1, 2018. It still has not fully merged the aircraft maintenance and technology planning systems. This process is expected to commence in 2019 and last around two years.

Recently, the carrier has told investors it has identified USD1 billion in possible cost savings through 2021, including those resulting from post-merger redundancies.

American Airlines finalised the USD11 billion acquisition of US Airways in December 2013.
