Speaking following the airline’s latest financial update, Johan Lundgren said: “It’s a decision for government, but we would expect that if they continue with the approach on testing they’ve set [and combined with the global vaccination roll-out], almost all major European countries should be in that category – by the time it comes to travel reopening.

“We still lack the scientific rationale why green countries should require testing at all. But if the PCR and lateral flow tests will need to be in place for green countries then I expect many countries in the category. But that is in the hands of the government.

Lundgren said he expected the government to be able to reveal which countries fall into which categories “not too far from now”.

“I have no indications for sure whether that’s going to happen but clearly we’re urging them to do that as soon as possible. That is now the big question that most of our customers are asking about,” he said.

He added some Mediterranean destinations were already suggesting they would not require testing for vaccinated arrivals.
