Do you know if they will deny you from boarding an airplane if you can't show any negative covid certificate?
The drugstores sell also "self covid test" But you don't get any certificate because you do it yourself. I don't know if you could use that instead.
Those PCR test are extremely expensive for people like me. It's just a random taxation in my opinion.
I simply gave up on flying since jan. 2020. All my traveling's I do by car. Or stay at home. I am considering in buying some land big enough to sustain my family and just stay there.
