gilesdavies,
I believe you are incorrect with regards Virgin, as far as l am aware they are no longer flying passenger flights other than UK Gov repatriation flights.
They are flying cargo flights only.
Also l would say from your statement, As long as people are healthy and follow guidelines laid down by authorities/airlines I am sure they will be fine.
How do you know you are healthy?
A good number of people have Covid 19 but don't know they have got it and are as such passing it on by touching many surfaces.
