I was reading someone saying he'd been on a flight for over three hours, he had to wear a muzzle unless he was eating or drinking, so he made a bag of crisps and a can of coke last for almost three hours. Despite having been sat within six inches of each other for over three hours, on landing they were instructed to keep at least two metres apart, as they went down the aisle to leave the plane.

The virus is clearly well behaved enough to know it hasn't to jump from one person to another when they're seated and eating, but the devious little bugger is liable to when people are queuing to leave the aircraft.
