After a full day at work, I will take the red eye to London Heathrow, and then onto Porto. British Airways cancelled the connection to Lisbon for no known reason. The thing with travel today is that you need to be flexible and calm. It’s crazy out there in the travel world. I booked a flight to Porto instead. My confirmation still says I have the flight to Lisbon, even though they refunded me. And then there is the big question of Covid test. UK says not needed, British Airways wants the documents uploaded. The EU might not accept the USA CDC paper document, but non Non-EU can’t get the digital version. Who knows!
