Earlier quoted context omitted.
interesting. this seems to indicate that Schengen countries decided on a national level if they wanted to do checks on their borders. I have seen hard passport checks within Schengen in Croatia, Sweden, Germany, France and Portugal. Good to hear the UK has improved. I should have mentioned I haven't been there since 2018. I was expecting that brexit made things worse and had no idea
This really doesn’t add up. Who was performing these hard passport checks? An airline employee? Where was your flight originating from/going to?
Dublin -> Heathrow
Frankfurt -> Heathrow
Stockholm -> Heathrow
... and as I said I have seen similar things arriving in Frankfurt (in 2017 and 2018) and other places (Dublin -> Zagreb etc)
