British Airways is to launch a voluntary Covid-19 test for passengers travelling to the UK from three US airports, APA reports citing BBC.
The airline wants to persuade governments that testing travellers will make quarantining unnecessary.
American Airlines is also taking part in the trial, which follows a similar effort by United Airlines.
The government is looking at how testing can reduce the time travellers to the UK need to self-isolate.
British Airways owner IAG has long criticised the 14-day quarantine imposed on arrivals, saying it deters people from flying and damages airlines.
It is also trying to convince the US government to open its borders to UK nationals, who have been barred since March.
