He should’ve done his part and rented a car. I just don’t buy that if this 737 was, say, 50% full the risk would be noticeably lower. You’re still putting people in an enclosed space for several hours with recirculated air. So spacing the same people out and putting them on TWO flights instead of one would really mitigate the risk?
See number 9. Airliners completely exchange cabin air with outside air every three minutes.
