I think we are now looking at a full scale grounding of UK based carriers along with mass layoffs. This is so much worse than anything before including 9/11 and the volcano grounding.
I would go further and ban all flights between UK and USA until the travel ban is lifted. The US health industry is not fit to deal with this any better than any country with a joined up health service so stop them coming here please and in any event it won't do the environment any harm.
`time to focus on family friends and staying well
