I took a plane from Italy to Greece a couple of months ago: completely vaccinated and with the Passenger Locator Form ready.
Nobody, literally nobody, checked in a reliable way wheter:
- we had a valid COVID Certificate
- our PLF was filled correctly
The only moment during my trip where anyone checked was at Starbucks.
This doesn't mean that you are entitled to lie to the border control agents though.
It's a bad idea to travel with false paperwork, as it's a bad idea to travel with anything illegal in your luggage, not because there's a high chance they'll definitely look into your situation, but because if they happen to choose you randomly then the punishment can be severe.
That's what I was responding to.
Fact is that people plainly don't know how official or authentic information looks like in case of anything Covid. Was at a barber last week and he has to check my vaccination status. I presented my QR code, she looked at it for a few seconds and then was already happy. You are supposed to scan it with another app but nobody seems to know this... Perhaps she can read QR codes in her head?
