I’m just curious (and I’ve tried Googling but the only articles I can find are from last year).
I can think of very few reasons why someone would fly in or out of the UK right now. Business travel is surely stopped for now. Holidays aren’t happening - even if someone came here for a holiday, everything is shut. Of course some people will need to rush to see parents who are elderly, possibly dying etc but there can’t be that many of those.
I totally support the government’s plan to quarantine people who fly in ... I’m just wondering who they are?!
