The union representing flight attendants at American Airlines Group Inc has called for workers to prepare for a possible strike following failed contract negotiations with the airline.

The Association of Professional Flight Attendants (APFA) stated that significant disagreements persist on key economic aspects of the deal, along with what they deem as unacceptable scheduling demands from the company.

APFA anticipates that the National Mediation Board (NMB) will facilitate a final negotiation effort within the next two weeks, Reuters reported.

American Airlines and the NMB have not yet responded to requests for comment. Lawmakers in the U.S. have urged the NMB to intervene to assist approximately 80,000 flight attendants in reaching contract agreements.

Flight attendants at various airlines, including United Airlines, Alaska Air Group, American Airlines, and Frontier, are among those still negotiating new contract terms.
