Flight attendants demonstrated at Palm Beach International Airport Monday afternoon.
The action came as American Airlines argued before a federal bankruptcy judge Monday that its union contracts need to be changed to make the company financially stable.
The airline lost more than $10 billion in the decade leading up to its declaration of bankruptcy in November.
The airline's unions say company leaders are unfairly blaming workers instead of doing something to make American grow and bring in more revenue.
"I'm a mother of two, and everyone knows it's a difficult time to rear children and it's heartbreaking that they can treat us like this," said one flight attendant.
American wants to eliminate 13,000 union jobs - about one in every four union workers - freeze or terminate pension plans, curb health benefits, reduce time off, and impose many other cuts.
