The passenger, who had previously been tested for the virus and was awaiting results, got a notification toward the end of the flight that the test had come back positive. The person was overheard talking about it, and the flight crew quickly notified health officials on the ground, JetBlue confirmed on Thursday.

“JetBlue had no prior indication that this customer had or may have had coronavirus,” the airline said in a statement.

The flight, which departed from John F. Kennedy International Airport with 114 people on board, landed at Palm Beach International Airport around 8:30 p.m., with medical workers rushing to a call at the airport shortly after, officials said.
