Further details on government plans to introduce a two-week quarantine period for people arriving in the UK are expected soon.
Any passengers arriving in the UK by plane, ferry or train will have to provide an address where they will remain for two weeks.
The idea is to reduce the spread of coronavirus by minimising the contact international travellers have with other people when they first arrive.
The government has not given a starting date, but has said it wants the measures introduced “as soon as possible”.
On arrival, travellers will need to provide UK Border Force officials with an address where they will self-isolate. Otherwise, accommodation will be arranged by the government.
The government guidance says all flight passengers should remain at least 2m (6ft) apart from other people wherever possible and consider wearing a face covering.
People travelling through Manchester, Stansted and East Midlands airports have already been told to cover their faces and wear gloves.
EasyJet has said all passengers and cabin crew will be told to wear face masks when it resumes some flights on June 15.
It previously said it would keep the middle seats on planes empty for a time. Emirates and the US airline Delta have announced similar plans.
However, the International Air Transport Association, which represents global airlines, says leaving the middle seat empty would not improve passenger safety. It also says most airlines would not have made money last year if a third of the seats had been removed.
Some temperature screening trials will also be conducted at Stansted. Heathrow, one of the world’s busiest airports, is already trialling large-scale temperature checks.
The government recommends international travel only when absolutely necessary and nobody should travel if they display any coronavirus symptoms.
Since that advice was issued, far fewer people have been flying. For example, between 16 and 22 April, the number of air passengers coming into the UK was 99 per cent lower than the same period in 2019, according to BBC reports.
Ryanair, for example, carried 40,000 passengers in April – down from 13.5 million in the same month last year. It expects passenger numbers to halve in the current financial year.
However, the airline still plans to reintroduce 40 per cent of its flights from July 1, subject to travel restrictions being lifted and safety measures being brought in at airports.
British Airways is reviewing its plans to run 50 per cent of its schedule from July, because of new quarantine rules.
