Three collective bargaining agreements have been reached between the new American Airlines Group and its employees at US Airways. American Airlines Group was formed in December when Fort Worth, Texas-based American Airlines merged with US Airways. The agreements were reached with mechanics, fleet service and maintenance training specialists, who are members of the International Association of Machinists.

According to American Airlines Group the agreements will stay in effect with the US Air workers until a collective bargaining agreement which includes all 30,000 of the Group’s employees is reached.

“We are pleased we have reached these agreements,” Doug Parker, chairman and CEO of American Airlines, said in a statement. “These agreements will allow us to focus on the next steps for integrating our airlines, and we can now start the process of bringing these employee groups together with their co-workers from American through joint collective bargaining agreements.”
