A new study purports to show 59 Covid-19 cases ‘linked’ to a single flight, but that’s somewhat misleading.
Inflight transmission seems to be rare, it certainly isn’t impossible, and someone with a high viral load and lots of shedding may overcome the best precautions. The virus might spread at security, in a lounge, at the gate area, or simply transiting the terminal. It could spread on the jetway as well. Flying is safe, but not totally safe. In many ways, just like going to the grocery store.
