A former Southwest Airlines flight attendant who was fired after sparring with her union president over abortion won a $5.3 million jury verdict against the airline and the union Thursday.

A jury in a Dallas federal district court handed down the verdict, ruling Charlene Carter had been fired for her religious stance on abortion, which she shared to social media, and that her termination was in violation of her right to advocate against her union.

If it stands, Carter could collect $4.15 million from Southwest and $950,000 from Local 556 of the Transport Workers Union, mostly in punitive damages.

Southwest said Friday that it 'has a demonstrated history of supporting our employees' rights to express their opinions when done in a respectful manner.' It plans to appeal. 

A lawyer for the union said jurors might've misunderstood the judge's instructions and it also plans to appeal.

Carter alleged she was fired in March 2017 after complaining to the union president about flight attendants going to the Women's March in Washington, D.C., in January of that year, where more than 500,000 people protested former President Donald Trump's positions on abortion and other issues. 

The longtime flight attendant, who had clashed with the union for years, believed dues were going to fund an anti-abortion protest.

Carter sent a series of Facebook messages, some containing videos of purported aborted fetuses, to Audrey Stone, who was president of the union at the time, calling her 'despicable' and saying she would be voted out of office.
