alt Hacker NewsThe different Heathrow terminals have different security requirements. I suspect it’s based on countries they fly to from each terminal, but it could be age if equipment.
It is frustrating for security to act like you’re a total idiot for following a process another terminal says is fine (like leaving very small electronics like Kindles in your bag).
Oh, well.
Indeed. Other airports in Europe even have separate terminals or areas for Schengen and non-Schengen destinations, with passport control and sometimes security scans again between them.
Bonus points to Zurich (Schengen but not EU, just to test the edge cases) - I think they have an airside metro where each car is segregated for a different security category of passenger.
