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.
