Virgin America has announced it will be cutting approximately 225 management positions as part of its merger with Alaska Airlines

A filing with Californian labor regulators seen by Bizjournal said the move aimed to remove all duplicate white-collar posts at Virgin America's Burlingame headquarters the merger would invariably create. The lay offs will begin on October 11, 2016 and will run until June 30, 2018.

Alaska expects to close the USD4 billion merger by December of this year. Operationally, it expects to attain a single Air Operator's Certificate (AOC) by the first quarter of 2018.
