I was checking for travel ins the other day. There are a couple of companies that will give you a policy (I think it was going to be about £75 for the Daughter), but not cover anything covid-related. So the usual stuff - missed flights, lost luggage, broken legs, they were going to cover in the US of A. But not Covid.
I will try to remember which companies those were - there were at least two, maybe three I looked at just last week. If I can manage to remember which ones, I'll post it here.
