Delta said in a statement Friday afternoon that the airline is investigating the incident.

Dr. Tamika Cross, an OBGYN resident at Lyndon B. Johnson Hospital in Houston, wrote in a Facebook post that she was on a flight from Detroit last week when someone two rows ahead her of starting screaming for help.

“I naturally jumped into Doctor mode as no one else was getting up,” she wrote on Sunday in the account that has been shared more than 35,000 times.
