Better question might be ‘What’s required to land at your preferred destinations’as lots of countries have different restrictions in place. Where are you wanting to go?
You need a PCR test taken no more than 24hrs before arrival and make sure that your flight doesn't transit in Botswana, Eswatini, Lesotho, Mozambique, Namibia, South Africa or Zimbabwe.
For Poland it’s EITHER a PCR or a lateral flow taken within 24 hours of going. plus a locator form for the Poles. coming back should be PLF plus a PCR test book for within the first 2 days.
He could be in trouble as most flights from Newcastle to Poland you have to go via 1 of those countries
Lateral flow can you just use a home test though? It was a piss take paying for pcr tests in August.. Lateral flow isn't too bad PLF?
Passenger locator form. airport lat flow tests are relatively cheap and fast mate. Grab a greggs whilst you wait.
