The leaders of several major airlines have written a letter to officials in the United States and European Union asking for a COVID-19 testing standard that would allow people to travel abroad safely..
American, United, Lufthansa, British Airways and other carriers want to establish a testing program that will "permit services to resume without quarantine requirements or other entry restrictions."
Currently, US visitors are not allowed to enter most European countries and if they enter the UK they must face a 14-day quarantine.
