American Airlines employees are debuting new uniforms three years after complaints they were causing headaches and rashes, among other illnesses.

The uniforms, manufactured by US based company Land's End have been given to 50,000 of the airline's employees.

They announced they were cutting ties with their previous supplier Twin Hill in 2017 after some employees complained of allergic reactions, according to CNN.

The previous uniform received over 3,500 complaints from employees who were members of the Association of Professional Flight Attendants.

At the time, Twin Hill refuted claims their uniforms included restricted chemicals but "welcomed the opportunity" to cut ties, according to CNN.​

In a press release, American Airlines said the new uniforms were created after three years of collaboration with staff and their union representatives.

Frontline staff members trialled collections at work for six months after consulting on fabrics and colour design before the finished pieces went into production.

The airline praised their employees and their union for helping them in the three-year process.

"None of this would be possible without the partnership of our union representatives, and, most importantly, the thousands of team members who provided input and feedback along the way." said Brady Byrnes, American's Managing Director of Flight Service Base Operations.

After the complaints with their last uniform, American Airlines confirmed that with Land's End: "All parts of the garment, including sewing threads, buttons and zippers, are tested for hazardous chemicals."
