Really LTNMan you need to keep up to date with world affairs. The 3 countries you listed are light years ahead of the UK with very few cases, so hardly a good comparison. They also imposed quarantine 2 months or more before the UK. Those countries were more concerned with imported cases, and like I said before quarantine works best when a country has a low rate of infection compared to others. The UK would be best quarantining visitors from hotspots such as all the Americas, Russia, India and if that was the case the airlines could hardly complain.
