As per the title, I can't get my head around how this all works. I know each company has their t&C's and time limits for changing booking but outside that is there such a thing as an insurance policy that will cover us if one of us tests positive and we can't go? I've only ever booked flights and accommodation separately previously but although loads of places offer free accommodation cancellation this isn't true for flights so are you better off getting a package? Helllp please. We only want to go to Europe for a week or so but it seems like a massive ballache.
