When American Airlines flight 341 to Los Angeles lifted off the tarmac at New York’s John F. Kennedy Airport on a cloudy Thursday in mid-March, much of the country was already on coronavirus lockdown. The flight was far from full, but the 49 passengers and eight crew shared restrooms, cabin air and a narrow aisle for the six-hour trip.

Though no one knew it then, a man in first class, a retired Manhattan surgeon, was infected with the virus. The day after the flight, he was rushed by ambulance to Cedars-Sinai Medical Center with a high fever and phlegmy cough. The virus spread quickly among those he had come in contact with in the hours after leaving LAX, including at a Westside assisted living facility where a 32-year-old nurse and a dozen others later died.

L.A. was still in an early stage of the COVID-19 pandemic when the surgeon’s flight touched down, with fewer than 250 confirmed cases. Local health officials regularly assured the public then that the county was investigating each case and engaging in aggressive contact tracing to control the spread of the virus.
