UK airlines say they have been told the government will bring in a 14-day quarantine for anyone arriving in the UK from any country apart from the Republic of Ireland in response to the coronavirus pandemic.
Under the move, passengers entering the country will have to provide an address where they will self-isolate for 14 days.
The new restriction is expected to take effect at the end of this month.
Industry body Airlines UK said the policy needed “a credible exit plan” and should be reviewed weekly.
People arriving in the UK would have to self-isolate at a private residence.
Government and aviation sources told BBC News that the quarantine would mean people might be expected to provide an address when they arrive at the border.
It is not clear how long the new travel restriction would be in place and whether non-UK residents would be allowed to stay in rented private accommodation.
UK airports suggested that a quarantine “would not only have a devastating impact on the UK aviation industry, but also on the wider economy”.
