A US airline has apologised after a staff member told a Satanist she'd have to change her shirt or get off the plane.
The shirt read 'Hail Satan' in sports-style lettering, and was accompanied by the phrase 'Est. 666' and a small upside-down cross.
Swati Runi Goyal says she was sitting on board an American Airlines flight in Florida on October 30 when she was told to take it off.
"I'm just an ordinary-looking person," she told Buzzfeed News. "I'm not goth. I don't have piercings. I wasn't wearing a shirt that had a goat being beheaded on it."
Combined with her hiking pants and "vegan sneakers", Goyal said she "couldn't look like more of a nerd".
She borrowed a top from her husband to satisfy the staff, but laid a complaint afterwards. The airline initially told her it has "policies in place to ensure that no passengers are subjected to objectionable situations while on board".
Frustrated, she tweeted about the incident - and the company quickly changed its tune.
"Discrimination has no place at American Airlines," American Airlines tweeted back.
Goyal soon got her ticket costs refunded and an apology.
"We apologise to Ms Goyal for her experience, and we are reaching out to her to understand what occurred," a spokesperson told Buzzfeed News.
Goyal joined the Satanic Temple because she likes its beliefs, which include "the freedom to offend" and showing empathy "toward all creatures". She's since made her social media accounts private after getting backlash from social conservatives.
