Still hoping to go but still a bit confused about current situation! My wife and I are double jabbed and have our NH certificates.As I understand it we have to have a lateral flow test when coming back and see that this can be done at Gravelines where we like to stay night before we travel back.But what would happen if either of us were unfortunate enough to test positive?We couldn’t self isolate for 10 days on an Aire nor would we I assume be allowed to travel back to the. UK.Then we have to book full Covid tests 2 days after returning which I assume is straightforward .but what’s this passenger location form about?
