According to multiple media reports, a Marine Corps veteran claims she was banned from a Delta flight last week because she wore a shirt that called for an end to veteran suicide.

Catherine Banks told NBC Bay Area that the incident occurred Wednesday when she was wearing a T-shirt that read, “Don't give in to the war within. End veteran suicide.”

Banks told NBC that she attempted to fly out of San Francisco International Airport.

“A male flight attendant said, 'Ma'am, ma'am.' I looked around and asked myself, “Who was he talking to?” And it was me. He said, 'You have to get off the plane,' and I said, 'What did I do?'” Banks said, according to NBC.

Banks could not be reached for comment Monday, but NBC reported that she learned why she was thrown off the plane by a flight attendant on the jet bridge.

“He said the shirt you were wearing was threatening,” Banks said, according to NBC. “I said, ‘Are you kidding me? I am a Marine Corps veteran. I'm going to see my Marine sister. I have been in the Marine Corps for 22 years and worked in the Air Force for 15 years. I will visit her.' He said, 'I don't care about your service, and I don't care about your service.'” The only way to get back on the plane is to get off it immediately.'”

Banks told NBC that Delta eventually let her get back on her flight, but she had to sit in the back and missed a connecting flight because of the delay.

Delta said in a statement to Marine Corps Times on Monday that the matter had been resolved.

“We appreciate (Bank’s) patience as we continue to work to understand what happened during this event,” Delta said. “Most importantly, we are grateful for their service to our country.”

The airline's website says flight crews are allowed to remove passengers from the aircraft if “their behavior, clothing, hygiene or smell poses an unreasonable risk of offense or harassment to other passengers.”
