(FOX NEWS) - An Ivy League professor says his flight was delayed when a fellow passenger mistook his scribbling on a math problem as a sign he might be a terrorist.
American Airlines confirms that a woman expressed suspicions about University of Pennsylvania economics professor Guido Menzio.
He was flying from Philadelphia to Syracuse on Thursday to give a talk at Queen’s University in Ontario, Canada. He was working on a differential equation, but said he was told the woman thought he might be a terrorist because of what he was writing.
Casey Norton, a spokesman for the air carrier, said the women’s allegations about Menzio were deemed not credible.
Norton told The Washington Post the woman had initially told the flight crew she was too ill to take the flight but when she deplaned to take another flight she disclosed that the reason she was feeling ill was her concern about Menzio.
