LONDON, ENGLAND - JANUARY 25: A British Airways airplane flies over a Premier Inn hotel as it comes in to land at Heathrow Airport on January 25, 2021 in London, England. The mayor of London is among those who have called for arriving travelers to be quarantined in hotel rooms upon arrival to the UK, in an effort to prevent new strains of the virus that causes Covid-19 from taking hold here. In other countries that have adopted this policy, travelers must pay for their accommodation in designated hotels and are delivered their meals during the period.
