An American Airlines flight attendant is suing the Fort Worth, Texas-based airline over what her lawsuit describes as an altercation with another crew member aboard a plane in June 2016, multiple sources have reported.

According to the Dallas Morning News, in a lawsuit filed in federal court on Friday the flight attendant said the other crew member “grabbed my scarf, choking me, and dragged me in the aisle and in front of the passengers.”

The Morning News says the lawsuit includes allegations of negligence, a dangerous work environment, breach of contract, and assault and battery and is seeking damages of up to $1 million.

An American Airlines spokesman, Ross Feinstein, declined to comment on the specific allegations, saying only that American Airlines “strives to create a work environment in which all team members feel safe and respected.”

An American Airlines flight attendant is suing the Fort Worth, Texas-based airline over what she describes as a physical fight with another crew member aboard a plane in June 2016, multiple sources have reported.

According to the Dallas Morning News the flight attendant, Kathy Ida Wolfe, claims in a lawsuit filed in federal court on Friday that the other crew member, Laura Powers, “maliciously dug her fingernails into my arm and slammed the door of a beverage cart on my arm.”

The Morning News reports that Wolfe said Powers “grabbed my scarf, choking me, and dragged me in the aisle and in front of the passengers.”

Newsweek reports that both Wolfe and Powers were employed by the airline in June 2016 and that Powers has been an employee of the airline since 1985.

The Morning News reports that Wolfe said she followed American Airlines protocol by reporting the incident to the captain, other flight attendants, and the flight service manager. But Wolfe claims American Airlines did not investigate the incident, so she filed a lawsuit against Powers and the airline. The lawsuit was originally filed in June in Tarrant County district court before being filed in federal court.

Reached by Business Insider, an American Airlines spokesman, Ross Feinstein, declined to comment on the specific allegations, saying only that American Airlines “strives to create a work environment in which all team members feel safe and respected.”

According to USA Today, attorneys for both American Airlines and Powers responded to the initial Tarrant County lawsuit by stating “not liable because Plaintiff caused or contributed to cause the harm for which recovery of damages is sought.”

The Morning News reports Wolfe’s lawsuit against American Airlines and Powers includes allegations of negligence, dangerous work environment, breach of contract, and assault and battery and is seeking damages of up to $1 million.
