It all worked.
The PCR test. The test certificate. The vaccination certificate. The Portuguese passenger locator form.
In fact Ryanair did not ask to see any of it (although I uploaded items 3 & 4 when I checked in).
Portuguese immigration asked to see the test certificate… and stamped my Brexity passport.
6 hours in a mask - bus, airport, plane, airport, taxi - is no fun if you are not used to it, but it is the way we are for now.
I will be in Porto for the next 6 days. The Blip is just a bit of my wee studio here. It was well after dark when I arrived.
