Most of the British carriers drafted a letter that they sent to the Prime Minister of the United Kingdom, Boris Johnson, and in which they ask for the return of the flights for the next major. The letter is signed by directors of British Airways, Easyjet, Ryanair, TUI, Virgin Atlantic and Jet2.com, among others. “There can be no economic recovery without aviation and we are confident that we have the instruments to allow a safe and reliable start to begin air travel in May,” the text states. “We believe that vaccinated passengers should not be subject to travel restrictions and that testing can also reduce barriers to travel,” the letter continues. Apparently, the United Kingdom would have decided to move towards a traffic light system, in which countries would be rated on three levels by virtue of the risk of contagion and the status of vaccination: red the most dangerous, intermediate yellow and green that does not present disadvantages . To travel to the first two destinations, passengers must comply with a period of isolation or quarantine in places determined by the government itself.
